Some derps:
Derpy water:
Random wool block in Osgiliath:
Arrow stucked in the Deeping Wall:
Some dirt in Forochel (also, underwater snow is pretty strange):
Some leftover wool, north of Lake Nenuial:
One too many wooden slab in one of the Emyn Beraid towers (also, can I ask why two of them are still on a floating grass square?):
Not really derps but suggestions:
Hornburg. Adding a path here would be defensively way more interesting!
Same zone (just next to the latter), also, there is no real way to get to this chest without jumping. I suggest to convert the selected block into stairs:
Still Hornburg, still in a defensive perspective, what about adding gates to the second rampart?
Aldburg. In my opinion, it would be better if these two little buildings of the gatehouse were accessible (with a window in the middle), cause the building looks like it hase been build for it:
About Rohan in general, I noticed that the roofs of Edoras have been updated from wheat (on the old map) to straw blocks but not the other settlements (pictures: Aldburg, but the same everywhere else). Why?
Still about Rohan, I think the gates of Edoras and the Hornburg should be opened or half-opened (like all the gondorian ones) instead of being pierced with a little door, cause it doesn't look good (the first picture is next my two latter suggestions for the Hornburg, the others are the main gates (and I didn't check if Edoras has other gates)) :
