I find the pose very strained.. looks very uncomfortable. The light falloff from camera left to right makes the photo increasingly dark and makes the skin look really strange. Between the light falloff and the water, her hand in the background looks "dead" like a shriveled hand thrusting up out of a grave or something. Skin tones are terrible... and WB is very cold. Perspective distortion looks really odd.. and the foreground "horizon" (tub) is not straight. You do have interesting framing with the tub sidewalls, but it doesn't really help the shot. Possibly a very shallow DOF would have helped.. as the background is not attractive... it just looks like a standard pre-fab plastic / fiberglass tub surround.. harsh, cold and cheap.
What were you trying to show, or say.. with this? What were the thoughts behind this?
Did you partially desaturate this also?
