This looks fantastic. I certainly love the feel of it. I like the idea that you used for the doors, and the simplicity of being able to tell which way they open out. Perhaps instead of using a white block, you could use a door, but have the mark similar to that of a building blueprint to indicate which way it swings outwards? Something still noticeable, yet less intrusive. The idea is very interesting, that it is built into the side of a chasm, love it The only other question I have is, why is it that one of the rooms (with the grates on the floor) is more blured than the other three? Not quite sure what is going on there.
