Dude that is looking like god's work but it looks like god (you) messed up a lil on the face. it just looks kinda bleek/dull make it seem more cold and dead the face just looks like a bad painting.
If there is no transformation i got a pretty ok idea for one buts tis gonna be hard to explain and since my imagination is very wide maybe very hard to do....
He should transform into a full Vampire demon look. Have large bat-like wings (if u can get some1 to animate them to look like their flapping when flying), Pointed long ears, Long Gray Tangled lookin hair, black eyes with red dots in middle, Legs bent backwards (knees in the back(not sure if that would look good), Clawed hands and feet, Brown or reddish brown skin, small pointed teeth, 2 large ones for fangs, Thin malnorished body.
I guess in will be very hard. tis just a suggestion i no it will be hard (hard thats an understatement).
Ok bye
