I don't have much rights to judge your work and I can see you put a lot of efforts into it, but in my opinion you focused too much on the "decorations" like birds or bunnies instead of simply exposing the architecture. Such ornaments are good, but when they are subtle. Again, this is just my opinion and I can also understand it if this was your goal.
Some technical stuff:
-some bump map/displacement on the trees close to the camera would make them look much better
-stretched uvs on stones
-too strong bump on the inner wood material, I can imagine getting splinters when touching it :)
-wood material seems too contrasty, makes it hard to focus on the whole interior
