Something I noticed in the second screenshot, something which really gets on my nerves, is that hanging platform. While the platform itself is fine, you need to remember that the model is designed to be supported by surrounding structure. The ropes have no tension on them, and it looks really unnatural to have bent ropes. Of course, this is easy to fix, just remove the platform and remake your own with some entity ropes. Of course that's just my little rant, I'll be back with some real feedback once I've run through the map.
