Stunning work intertwining the two. The shadow, lighting and particularly the depth of field work very well together. I saw a few of the other comments about things being out of focus compared to her, but her feet are in similar focus to the part of the book she is standing on, and her body and face are in similar focus to the match and the corners of books at the same depth. No Photoshop work can ever be perfect, but this is a considerable approximation of it.
Great work, really. Almost perfect. The girl is a bit too in-focus respect to the closest part of the environment, which is a bit blurred. See for example, the books and the matches. Also, the refection on the glasses is a bit odd.
Oh Well, this is just comments from an occasional judicial expert, so don't bother taking it into consideration!
