This just turned into a collaboration. Thank you for your cc, Warrior. I hope this hair will satisfy you.
You may also notice that I improved the left eyebrow and eye.
is looking cool just needs more work on the hair and remember the right side of face is not black but shadowed, i sugest that you may try to turn in to shaded not black skined colour ;)
Your hair making technique isn't the best. Essentially, you want to put in different shades in with a small brush, then smudge it so it looks like hair.
Removing the shading division and focusing more on the illumination of the scars.
Adding more scars/symbols to the other side/forehead/eyeline to create the sense of it taking over.
Not sure about the hair yet. I'll see what happens once the rest seems done.
