This is great, but the first thing that popped into my head without a second thought was that he was reenacting titanic. Probably because of the little icebergs. It's really a great picture. I just have stupid thoughts.
Interesting concept. I like the effect you used on the part of the boy's(?) legs and torso that are underwater. The details you have on the tubs sides and edges are remarkable and time consuming, I'm sure. oh, and I like the translucent look of the ice, nice touch. Great job overall.
