Wallpaper test

I felt like drawing again so I decided to draw myself a wallpaper. The problem is that it doesn't fit

I found this beautiful photo [link] so I used it as a model for that posture.

I'm still trying to get used to my Wacom tablet so there might be a lot of mistakes.
Tools: Photoshop cs3 and Wacom intuos3 a5
