The haze gives a good sense of depht.
The highlights, rimlights and color transitions really help defining the type of "materials" (lava, stone, skin, shell etc), this is what like most in this picture.

this has to be front paged, there is no other way is too damn good!

I might turn this into a DOOM monster.

For some reason reminded me of old mortal kombat videogames,but with more metal attitude.I love your work man.
