This was really hard to vote. (To tell the truth I can't remember in the end which one I voted as I find them similar close. ) The fishes are a nice touch, both for the feel and to show a bit of water effects. I think the strongest point of this is the dynamics of the entire scene.
Nicely done. What I think it is it's worse point it's not modelling or painting but photography. I think the almost offwhite background hurts the miniatures feel a lot, taking it out of context and also loosing the surprise feel the miniature has. Also I think you should have had different levels of gloss on ground and fabric (make again is camera) to emphasize the different wet materials?
Wow just wow. One of the best bronze entries. Hats off to you. But if'd be to split hairs here I think the circular wave around her should have a different shape (less round more elliptic) in the back and maybe a bit higher? Since the ground level under the sea is also higher? (I'm not sure exactly, but probably some experiments would give you the exact change in a wave based on different levels of the sea base in shallow water). Also I think the monster should have had more slabber around/down the mouth?
