My first impression is that this is very dangerous because what happens if the camera gets wet. Nice image. Color seems a little off because normally we tend to think that shower walls are white. But the case could be different for you. I like the focus and composition. My attention immediately goes to your eyes and that is where you want someone to start IMO. The water also has a nice motion blur to it although a little lost in the shower wall at first. The DOF I think is a little off and your elbow takes away from the photo. I would say either make the DOF so that the elbow was in focus or crop it out. I think cropping it would hurt it more so my opinion is to try again and put everthing in focus.
