I am fascinated by the fact that, to my eye, the guy on the left looks a little scared and nervous, while the guy on the right looks confident and a little arrogant. And yet, they have almost exactly the same postures and expressions.
The backdrop is an interesting choice, definitely a bit different than the urban-gritty you'd expect for a couple boys like this.
What's up with the guy's hair, on the left, where it thins against the backdrop? Is that just compression artifacts, or is the lighting doing something weird there? Or is this 'shopped in some fashion that I am not quite understanding?
I like this, basically. It's interesting.
