Modeling looks really good, but I think the "material" looks kinda like rubber, the rest looks pretty cool.
My op

Thanks weiqicui glad you like it , yer does sorta look a little rubbery, I was trying for a blood dripping squishy sorta look, i think if I had a fluid or partical blood dripping it might look a little better 
You should really continue with the rest of the body, this demon dude reminds me of Diablo (silly, the game). Do some expressions with deformers and animations, I really want to see the end animation if you gave any thought about animating this d Dude.
Cool.
