HAHA!
When I first seen Wenger in the original pic, I thought of putting him on a horse. Class. A touch of motion blur and it would look even more realistic.
If there's one thing I've still to get use to in PS, (for convenience sake) it's cutting out shapes and getting the edges perfectly smooth without any background artifacts from the original image. How do you do it? Is it just a case of using a masking layer and selecting it to cut it out?
