Its nice. I'm instantly wondering, though, what they're looking at. I'm sure you couldn't include it in the photo, though. my eyes are drawn to the left of the photo, though and then I have to stop. I want the photo to keep going!
The focus looks a little off, but that's really no big deal. It was probably an auto focus issue, the lighting looks a little less than adequate. It looks like maybe it thought you wanted to focus on the background, but your aperture was deep enough it didn't matter? Either way, its still a cool photo, and the looks on their faces combined with their clothing make for a very compelling subject! I want to see more!
