I think they all look great as well. Only criticism I would have would be in regards to the PS photos and working on matching lighting for the shopped in images to help blend them better. So the illusion of a single photo is pulled off better. But I see in some of your pics, you've done that. So yeah.. great pics and work!!!
I also enjoy movie special effects and I thought since this is my picture effects thread I would put these here as well. I have many more on my computer but only a couple on youtube at the moment.
