If its critics you want then:
Background blood seems dried up becouse of the light red color.
Blood on the character looks like it needs depth.
The wounds, or scars are a bit odd. If you ask me they resemble small pink leafs.
The smaller hairlines could be more subtle (if done with the computer try lowering oppacity)
Thats all I could find for you.
Very good work there.
Mmmm, thanks for the comments (even though apparently you people are very bloodthirsty O.O But that's why you're awesome).
As for the blood, yes, I had much trouble with it. Every time I tried to shade it, it looked very bad and plastic-y. This was the best I could do for now. But I will try the smaller hairlines thing next time.
