really good !!! When I was 11, I wasn't too good at drawing. Keep practicing and you could be a quality artist. The body looks good, and the hair is okay, but try to even out the face a bit. The eyes need work and are kinda low and too far to the left, but still look okay. You should totally save up for a drawing tablet so you can practice drawing digital art and to me it is easier than using paper. Do you have a tumblr?
I drew a lot of anime when I was younger too. If your really into drawing maybe you'll want to check out my YouTube channel. I just started recently so there's not very many videos. I'm going to me making videos with how to draw certain things. Maybe you'll be interested in that. Feel free to ask me questions :)
