Floating chamber

Overall this looks nice.  The lighting, anatomy, and pretty much everything about the girl is well done.  Male figure seems off.  He has a very ridged pose, which is in part due to his clothing.  The overly soft edge of the botom of his robe could probably be hardened a tad.

I think the overall lightning could show materials a bit better.  What are the walls/pipes/carpet leading u to the chamber made of?., the background walls look like they could be concrete.  The pipes are likely metal? but their refelctivity doesn't really show it, there's almost no bounce light.  All of these things are pretty subtle, but can really help make the place feel like an actual space. and I think the image reads really well either way.   

take my comment with a grain of salt, I don't have much experience with interior design/materials like this.
