I'm really liking what's going on with this wallpaper. Although, some things don't flow too well. I think you take of the caution text completely.

The background and the scan/image you used still need to "blend" (you can say) together. Maybe a bit more white abstract brushes around the border of the image of the girl -- so it won't look like you just extracted an image and plopped it onto a background and didn't do anything to blend her in.

Needs a bit more work, but I like it. It's refreshing to see this kind of style.
