Thank you for your application! It has now been checked and here follow some tips on what you can improve on to increase your chances on a promotion to Artist.

On your Helms Deep Themed Build you did experiment with some new material combinations, e.g. on the floor or with the blackish cobble in the walls. Experimenting is always a good thing to do, but it also needs evaluating the outcome, and the combinations you used now do not look that appealing to my eye. A criterion on what combinations look good and which not is honestly hard to give, hence you kinda just need to develop the feeling on that, so that you can judge yourself which material combinations look good.
A second thing you can yet improve on is the interiors: A good example is the corridor on page 30 of your google doc. Here you could make it look much more interesting by e.g. making a nicer ceiling, by using stairs to add some details to it. Furthermore the crates and other things you added often look kinda out of place, again its hard to tell what exactly is the "problem" there; I guess it is because you mostly made piles of one block/type of crates while mixing different sorts may look more random and lively. Also the log pile looks out of place as it uses a default texture (which doesnt combine well with MCME RPs)
For further feedback please ask an Artist or Designer ingame or submit some more builds to your app.

Also please note that the criterions and the way artist apps are handled in the future are about to change. Further information will be published soon on the forums.
