Although idea4 seems a little simple with so few elements in the picture, each of the animals will need a lot of tweaking as they both have lots of spines. I am also thinking about darkining the fish further and then giving it bioluminscent organs along the side which might help add some mood. The front “copepod” needs a lot of colour-tweaking to give it a transparent look. I’ll cheat and let it be slightly illuminated even though this is going on deep, deep down in the ocean 
Any crits/comments/booh’s are welcome
