I'll post my tips later for both. I finally found some time.

Ok @willgreen1
You need to take more pictures. Most of your builds only have 1 or max 3 pictures with some not being good enough to see your building skills. The app is intended to show what you can do building-wise and right now I don't think anyone would be able to correctly analyse your talents.

So go out there and take at least 3 pics: 1 front, 1 back and 1 interior. The first two should be taken in birds-perspective aswell so you have a clear overview of the build. If the build is larger try to make a diagonal overview picture and more interior pictures. If there are any highlights that you want to show, put those in too!

Looking at your overall pictures I'd say that you build very basic. This is a good starting point to start learning but I don't think you are artist level yet. I would go start practicing by copying already done builds to learn how to do details, styles, shapes and so on... Go build a minas tirith house on main and try to get an artist to give you some feedback and try to make changes where needed. Ask if someone could show you how to do certain things so you got that in your skillbag.
Another tip would be to check out builder school and copy the houses on level 3 (fornost, rohan, shire, trees and shapes). If you have more pictures of certain bigger builds like the houses of healing, I'd be glad to recheck it.

Not yet, sorry jcw to be so late with this but I've been occupied lately and I thought someone would have helped you.
First of all, your build looks alright. The general idea is good and the layout is fine. What you need to adjust is your style.
If you look at the halls and caves you notice that you have a lot of flat parts and symetrical-looking parts. I can guess it would take a lot of work but try to first go for a realistic cave layout and then build the rest around it. Avoid flat floors and walls and sharp transitions between the two.
This is what I mean. That picture doesn't really seem artist level and doesn't show a certain goblin style. Think goblin tunnels, sketchy scaffolds, chaotic roads, dark corners and so on. Those things aren't what your theme build shows. It could be something else than goblin town.
This is also an example of what you'll have to avoid. I'm not talking about the island or stalagmite but the flat floor and sudden transition into the water. It doesn't look rocky or cave-like but just man-made. Try to build more smoother and curvy, a good tip for you might be to after you're done building, go and reshape somethings and think of how the build would look like for someone else who wouldn't know anything about it.

Teah I looked through though and do have tips to give but I feel I wouldn't be able to properly help you by typing it. I'll be online on ts every evening from 21:00 gmt+1 till 23:30 or later. I'll keep an eye out for you too.

Ok @spike010
Not a bad try for your first time, but not yet completly the real thing.
What you want to try to avoid, is building trees like a coat hanger and try to build fork trees.
This might sound really weird but it's a perfect methaphore for tree making.

What you start off with is a sort of trunk with many support branches on the sides, much like a coat hanger: a central seemingly straight pole with several pegs on the side with something hanging from it.
While some style of trees use hanging foilage, that don't have that support structure. Their leaves just tend to fall downward but the branches stay the same shape. What kind of shape would then look better?
Well there are several basic tree shapes you can use/think of that work better in minecraft, but the easiest one in my humble opinion is the fork typ.
Imagine a fork which doesn't have a long handle and has many different teeth in all shapes and sizes. Prick that fork into a salad of leaves and you get a tree.
By thinning out the central trunk into thick branches that go opposite ways, you can easily create a canopy above it that looks real. It's a bit more complicated to actually make such a thing in minecraft but luckly someone made a class with good examples of what I mean. Go to freebuild, set your gamemode to survival by typing /gm 0 and warp treeclass. (Do not break any signs here and tell me when some are missing. If you accidentally broke one, tell me right away!)

@Dargona1018 Sure, why not? 1 problem, I have very few time on my hands and I try to divide it between jobs and regular stuff. So make me a pm and we'll try to fix a date.

If anyone has any other questions about a personal build or something, and want feedback, I'd be happy to help.

Alright, with that input by dargo, here's my advice for you.

@arathorn867 Looking at your survival pictures, it strikes me that you did put a lot of time into minecraft stuff and that you also have some experience. That's really useful for later, but I'd say you lack the experience that mcme gives creative players/builders in this process. This is good news, since that generally means that you need some experience and maybe learning some mcme techniques.

So, your carn dûm theme build, let's sum up the pro's and the con's:
- looking at the layout I think you have a great 3D creativity which will prove useful in everything on minecraft. The buildings look organised and you try to give the building a story which a lot of people don't even try to do. Keep that storytelling talent.
- you go for an own style, which doesn't prove to be so bad. Trying to create stuff like this, is probably the first step to bigger leaps. Don't be afraid to continue that
- you do lack the technical skills to execute what is in your mind. You make certain basic errors on construction which are easily fixed and these skills come with practice and learning.

Several tips for you to remember on theme builds.
- look for inspiration. You have the entire internet to try to find examples of some styles or try to draw inspiration of the real world. I'm not talking about general things but more architectural elements. Ask yourself how this building would be supported, how old is it, which materials are used,... For instance, for osgiliath I try to look up a lot of renaissance buildings and roman architecture for structural designs and ideas.
- Flatness is your problem a bit. You can see this on the last photo of the theme build album, the main shot of the entire building. If you look to the right hand corner, you can see that there is a flat wall without any design place there. The diagonals are also a bit too thick and leave no room for intricate detailing. Try to build a bit slender and thinner if you add details. Otherwise some things might come out as fat, thick, flat and monotone.
- you should try to incorporate more circular stuff. I don't see arches or domes, everything is really symmetrical and straight. One example would be the triangle shapes on the front walls. Those might look better if you use arches and change the design every line. It doesn't look lord of the rings like.

All in all, I think you need to get some experience in building on mcme. Try helping on jobs, check out buildings and pay attention to construction, try to copy a building just to see how it's made, do scouting, check out the builderschool on the freebuild (warp builderschool) and try to copy some of the house tutorials, and lastly take a try at making an osgiliath house on the plotworld (look on the jobs and projects page in osgiliath post for more info). Try to help on jobs as much as you can so you can get a feel of the way things are constructed.

Good luck and if you want more tips, try to catch me on teamspeak! (or pm me)
