Wow... this is so cool! I love the contrasts - between the two guys hugging and the two guys walking away. It's so bold and eye-catching. You have created a very provocative, striking image here. Good job, and awesome use of selective desaturation!
Great concept and great shot. There's some spots that didn't quite get desaturated, though, that a little more attention (or perhaps a different desat technique) could have taken care of.
