Nice shot but, I think it would have more impact the the picture was a crop of just the guys in the middle there ...To me the guy watching on the right adds nothing to the picture.
It's a nice moment though it's a bit unfortunate that the focus is on the guy to the right.
It is also extremely strange to have the left guy's right shoe disappearing into the ground.
I'm of the opinion that this picture would be more suited to B&W than colour as it is somewhat monochrome already (e.g. the lighting is very flat and and the guy's clothes are alls black and white).
Regardless of whether the picture is in color or B&W the contrast should be increased. The easiest way to do this would be to do an autolevel in Photoshop but a slight s-curve would also help tremendously - //www.outbackphoto.com/workshop/photoshop_corner/essay_17/essay.html
