Deep Storm Online Key Art - Submarine and sea monster battle

An illustration made for Deep Storm Online, an unreleased 3D MMO submarine adventure game.
I got a lot of feedback from Loris, and he did overpaint for this same art piece in his account here:

I wanted to bring a thrill to the piece by making the monster come from the darkness at a high angle. With red and blue, I highlighted the main points of the illustration. It was hard since the pic looked like it was taken from space and not from underwater as intended. It was fixed with bubbles and making the background foggy. The submarine looks a lot like a spaceship which gave a good challenge. Please, let me know your opinions on the piece!
