Normally, your hair isn't glued to your head, so it isn't that flat. Try to give it a bit more personality. When I draw (I understand you used a base, this works too) I make sure to draw the hair not exactly attached to the head, so it gives it a bit of character. Also, look at the front of the hair, does Maryland have bangs, or even some form of it? Not all hair flows back naturally like that, so just make sure it just falls down along with gravity.
Nice base though! I use them a lot (not necessarily just plopping hair and clothes on them, but rather trying to recreate them on my own) and they're really helpful!
May I suggest a free program called Paint.NET? It's my primary drawing program, and it's more advanced than paint (considering the fact that it can do layers, which is a big advantage, especially when you're using bases)
*nods* i'll look into that. Unfortunately my computer has this thing where if I download something I have to have the administrative password to make it install on my computer and my dad knows the password but won't give it to me
Aw that's sweet ^_^ A little critique: with the hair, try to give it more personality. And maybe look at your own hair in the mirror or some hair on the internet. Most hair falls in front of the ears unless it's being pulled or tucked back. And then it normally curves differently around the forehead. If you look at some real photos or your own hair, you'll see what I mean. Keep up the good work. You get better every time.
