You had a good idea, but since VCS is probably going to be after VC (although not confirmed), you shouldn't have removed that building. Insted, you could've added a new or re-textured the old building. Also, instead or removing Tommy, perhaps you should've changed his shirt or make a new character. Oh, re-texture voodo, add a few new peds and cars.
But I like the idea of comparing the original with a fake screen.
Keep up the good work. And instead of using the healing brush so much, try using the color brush tool. You'll get interesting effects. Although I got to admit that healing brush was my favouite tool when I've started with Photoshop.
