Beautifully done. I've found coloured pencils to be very easy in creating illusion of light and dark. Shadows are a lot easier to blend and make look realistic. You've done a very good example of that with this
Nicely done - I find it easier with pencils when I want to do lots of shadows. It worked very well too, in this case. It nice the way you've "cut" the dark background. Funny thing is when I saw it as a thumb on main page - it looked like a beautiful stamp. I also like the way you managed to do the eyes of the subject giving them the illusion of light!
