Hey Queen,
Thanks for your app, I visited your build and I think its better to generalize on certain points here then leave small comments there (like I did for other people):
I guess it could be very possible for the terrain to look as you made it, stony, and almost desert like, however this is really not the way I vision any part of Eriador at all, and using the same stone variation looks quite boring and bland, also this terrain you made is in some awkward shapes. Your small stream is good though.
Your trees need a lot of work, I know you are trying to get that imagery of thin and small but the results are a bit derpy, I would visit /warp stctemp to learn more.
Your building to me doesn't fit into the more quaint and medieval look I envision for most of Eriador. Maybe adding another story to one part and adding another shape to the base, would make the rectangle/flat structure you have now a lot more interesting. The stables themselves in my opinion, are wrong shape.
Your structure inside needs more support, even though it's broken and run down, the support should still be there or the whole roof collapses.
If you could also upload these pictures for your application to an imgur link
Imgur as its looks much nicer.
