Well, having already seen your Hick and other drawings from your "new" thread, I'll just respond to this latest piece by saying I'm very impressed by the degree of professionalism in your artwork, especially at your age. Don't think I'm trying to be condescending or patronizing, either, since I'm only a few years older than you.
Your coloring is fantastic. It seems you've got contrast, shading, and shadowing down pat.
Some have noted that your proportions are out of shape. I'd recommend taking an art class in highschool, which is where you'll meet all the trippy, cool kids. I did, with almost nil artistic skill, and it was a blast. Besides getting all A's with your already impressive talent, you'll also learn proper techniques in proportion and get to learn about all the trippy, cool kids who grew up to be Edward Hopper and Andy Warhol.
Keep it up.
