Now it looks better. Thanks for advice.

Just something like this: i1034.photobucket.com/albums/a426/Zach_Masta/afro.png

Just enough AA so that the jaggies don't distract too much

or, you could always just improve the linework in those areas and not have AA

 You mean to put AA near afro inner circle or use AA on outline of hair?

:)

good first piece!!!

but, could use a hint of AA to make the circular zones rounder
