Something about the black power movement (1960s and 1970s).
What does Funky means?
I think you can, just make sure you checked the box to submit to weekly challenge I think. Looks better now!
thanks by the comment, I will try adding some shadow to the hair, can i edit the pixel art after submited?
You've done such a great job shading the face and collar, that the black hair looks unfinished. If it's for the weekly challenge you could use a couple colours for highlights in the hair
