Nice job, very pleasant to the eyes! I think I'd stick to the darker version too. The brighter version is too desaturated and feels like it has been through those popular instagram filters.
I like the scene, very believeable and all. Plus it is easy to feel immersed in it, for me thats a big deal. Too bad the cracked tiles seem flat on the cracks, you can clearly see they have no depth from that camera angle, and have some odd tiling. Not that it is a big thing though.
