I’m thinking the bath dominates too much of the scene. The ceiling/arches architecture is pretty cool (although as usual I beg to differ with your colour choice) but it is completely obliterated by the bath…the water in which is not that great.
Bringing me to the next point.
The water is not that great because at that angle, it would be almost completely reflective. Tweak your fresnel settings. Also, the strange reflection coming from an unknown source doesn’t help.
The bath tiles themselves, though, are pretty cool. And I like the lighting.
In general I think it’s good. Just too bad you didn’t put it in WIP or focused critique. (Disclaimer: I do not hate this image, and I do think it is art. Please do not freak out.)
(and tcrazy, he’s right. Take a bath. The water is clear.)
