this took less than 20 min to do. (and the shadow was done from an outline of the girl...)
All you did was cut me out and past him in, and then paste-into a slanted square that fits into my hands.. would have taken 10 minutes for a novice mr. professional =) I'm not sure how gimp works, but what you did utilizes only the most basic abilities of photoshop.
If you used the outline of the girl to do the shadow, whatever macro or program you used didn't really match up the lines too well o_O
The line of the shadow goes straight down.. it should be an outline of her head and shoulders.
