I like this creature, skin details just fit to the surrounding terrain, which makes it more realistic. I like how the red lines are glowing... it is cool.
Just off topic: here is what makes me confused :D why hide genitals? That pubic hair does try to hide stuff, but if this is a wild beast then it shouldn't care about hiding stuff, and if this sing is sentient, then at least it should wear underwear or armour or I don't know :D
P.S. this last paragraph was all off topic, nothing to do with this particular artwork but just judging from general point of view. :D
