I like the second one best. There's, like anticipation in the photo, as he's gonna rip into that corner. Nice batch of shots, not sure on the second pushing up one though, seems a bit boring in comparison.
I love them! They would make awesome posters, thats a buisiness opportunity there. Seriously though, as I am new to this photoshop lark, when you duplicate a photo like you have, are they just two layers ( or raster things)?
