Ok,

I removed the dithering and changed the colors.

But how should i reshade the hair??

No offense, but this seems like a pretty big step down from your other works.. Were you limited to just those 6 colors, without being able to modify them?

I don't think the red as a dark shade is working, and neither is any of the dithering, or the noisily-shaded hair.

Don't get me wrong though, I love just about all of your other recent works, especially the birth of Griffith.
