Excellent composition.

I'm glad you removed the red eye from the negative space, this works much better in composition.

Very lovely.

I like that there are two divers - though I agree his left hand looks a little large. 

Very Lovecraft. I am favoriting this sucker.

It's way cool! The enemy is an overgrown amoeba out to catch lone divers!

the lighting works so well

 It's caricaturized when compared to the rest of the piece and especially other diver, which is very beautiful. The one on top seems fat with very short legs and arms and a huge left hand. A few minutes of more work would make it a lot better.

Btw don't get me wrong, the piece on the whole is amazing, as I said in the first post.

Very nice use of negativve space.

 How so?

really interesting

Nice little piece, which surely would be great fun to get a higher resolution for more intricate details.

Awesome except the diver on the top. It kinda ruins the piece.
