The Dark Knight Part Deux

My first attempt using advanced photoshop. Making the Joker appear to be creeping up from behind Batman was extremely complicated the first round. Then as I was finishing up the final touches, the photoshop app hanged and I had no choice but to close the whole thing. The second round, the app hanged again and I, irritated, left this project hanging for a few hours. Well, you can say that third time's a charm's a cliche but I believed it after I got this project done the third time around. The great part of it was the main setting was dark which made it easier for me to combine The Joker's scene with the main layer.
