Oh thanks for this nice comment. I don't have msn or aim, I'm sorry.
The shading was mostly done with pixel-by-pixel dithering. you know, the dark color, the lighter color, agin the dark, the light color... and so on.
I should edit the description, when I've done this pixel thing I was too lazy to do the hair like it is now, now it's edited and I've added shading.
