also, jj, what i did when i made kevos sig, its fairly easy it just takes time. i first, got a pic of his car, the i trimmed it up making it smaller.
then, i found the picture i liked with the girl raven riley, then, i clicked the poly lasso tool and traced around raven riley, then i clicked edit/copy. and then i clicked kevos car and hit the paste button. after that, you select the box tool at the top left of the tool bar, and right click raven riley, then go down to FREE TRANSFORM AND CLICK IT. then, WHILE HOLDING THE SHIFT BUTTON, make it to your decired size. after that, i set the opacity a little lighter to blend in with the piccture. then, after that, click the SMUDGE TOOL and go around the raven riley pic, and try and blend it with the picture. after that i just made a border and put his name at the bottom right...
it takes time but once you get it, then its not that hard.
