Yes, you might have seen this picture before ^^ It was deleted because I did mention that I used a reference picture, but I had forgotten to add the link.. So here it is with the link :P : It's an artwork from a great artist on dA, shidesha ^^

It's my part of the artrade with SaxGirl, i'm really glad how it came out. The scanner became a bit evil again, the cookies of the dark side were too tempting for it :P
Mediums used: pencil, ink pen, normal/ordinary colored pencils and colored pencils with the brand Lyra ^^
