Amazing
This is quite fantastic, especially for a 17 year old. I hope you're going into some serious art-direction after school because I can't imagine how amazing you'll be after some tertiary education. This being a review, I probably need to say something negative, but all I've got to say is that you look a few years younger than you do on your reference pic, but only by an extremely short margin so no worries about that. I think it's because the drawn image is slightly lighter but it might just be me. Anyway, remarkable work. I'm sure you'll be going places real soon.
Also, a sidenote to philos27g, the reference photo link isn't broken, you need to remove the spaces in the link (in "me*dia" and "QA*HJI"). I think it's because URLs are forbidden or blocked.
