It's all a bit blurry, and many of the lights don't convince me. For an image that completely supports on the use of light it's not a very good one, I'm afraid.
In your image, light shines from above, right on it's head, which doesn't make any sense since we're deep underwater. The only lights should be coming from the holes. You could've played with those for some cool effects.
I like its mouth, don't be angry :3
