I love the way you did the vector. The texturing is really neat, especially on the lips; makes the whole face look more realistic. Though I would question that little blob on her nose. It feels a bit too dark in constrast to the surrounding face.
But overall, a very well done wallpaper. I think the old paper effect wall very effective. And looking on the scan you used, I think the way you simplified the part you extraacted into only that which is necessary in your vector really enhances the image in the vector medium.
Good job! :)
