I don't think you stink at underwater scenes--nice haze effect, it really gives an underwater feel! And the green gives it a different look form the usual blue or aqua. My only criticisms would be: i think the ocean floor would look better with some bumpier texture and I think the shark (if you have a program to pose it with) would be twisting around a bit if a big squid was grabbing it. (I know I would! :P) Cool picture, overall!
