Well, of the two shots of this bath, I prefer this one! It tells more of a story with what it doesn't show. Good focus and exposure - presented in a way that feels quite voyeuristic. My only comment is that the viewpoint (eye-level) is not very imaginitive. It could have been shot from any number of points that would have created more atmosphere. peeping from behind the curtain for instance, or from the edge of the bath with same human hair hanging over the edge?
I think you need color for this to work... presumably the dark stuff is blood, but blood is red! This dark stuff could be anything. lacks the visceral impact it needs.
