Hey there!

So first of all, your terrain. I really like the depth you have in the terrain - it's really creative and original, and it has a purpose. However, the majority is only made from stone, and it has no details until you reach the very top (not including the vines). It'd be really nice if you mixed the stonebrick in with all of the terrain, not only sections.

Secondly, organics. You don't have any.. It's always nice to have a small organic on a plot. This can be a person, an animal, or a plant of some kind. It's most commonly a tree.

Lastly, structure. Again, you don't have any. I like the idea of having it be like a raided area, but that's easy and one of the least creative things you can do, because it doesn't show any structural detailing or depth.
Please add an actual building.

Good luck!
