First, The Outline Is Really, Bad, I Mean i'm not trying to be mean or anything but i have to say it. I mean look at the outline of the hair, Some of the parts doesn't even have Black Pixels. The Back of the hair, Same thing, the outline is terrible, Anyone can just look at it and tell it doesn't have detail. Plus, The roots of the hair, Is really Clustered. And Like Leon Said, Get a Palette, and developed your own style. You'll Improve better that way.
