Of course he doesn't have to use them, just throwing them out there.
To get the "shadow effect (not sure if that's what it's called, butn that's what I'M calling it)" I used the extract tool to get my images, then used created a brush from the render. Then, the rest is history and clearly seen (this may be common, IDK, but I thought it would look cool).
Hope there are some other great submissions, and that your buddy feels better.
PS: I'm not too good with backgrounds as of yet.
