I didn't score this pix very high because almost all of it is out of focus, I can't tell whats not quite right if I can't see it. If the focus is whats not quite right,you got me,I didn't get it. A higher point of view looking down on the drain and the crabs,keeping them and the drain in focus would have let the viewer in on the fact its a shower stall with crabs.
The title was the only tip off that it was a shower stall.
