WAI! God, I love your style, and she really looks great! Though for advice, whichever program you're using to edit the picture after it being scanned, like on PSP (yes, the evil thing but useful) try using the Brightness/Contrast tool to give it more black AND white values, where you don't have that annoying greyness in it. Mess around with the contrast, though, never the brightness.
But other than that, it's a GREAT picture! I wanna see more of her in the future!
O.O Dear GOD!!! I think that's the coolest thing I've ever seen!!!! I love her hair!!! Everything is so awesome!! I wish I had half your talent!!
