Here is a small change. I made the texture map darker, but it didn't change the rendered version very much... then I played around with the lights. The sharks just don't seem dark enough. I excluded the sharks from two of the three lights in the scene, but it took too much off - made each more like ghost shards - shadow sharks, sharks who know what lies in the hearts of men. I was thinking of adding jelly fish - common in the cold waters, don't want to add too much clutter. Suggestions?
