Thank you! 
Your welcome! I am not that great at realistic sketches, but it appears you are!
Haha thanks! And don't worry. All that realistic sketches need is practice. I've been doing this kind of thing for a long time and no where near a perfect drawing yet. Just keep drawing, no matter what people tell you. The more you go at it, the better you get.
Yea, well this picture is AWESOME!!! I recently did a john lennon oil painting in the stylings of peter max. It came out really well!
