Nice shot Bart !
I agree, the look is really interesting. I see a lot of focus and determination in his eyes.
If you permit a critique though, I find my eyes tend to be more attracted to the second man's feet as the mattress plies create very strong lead-in lines towards him. It is actually a really interesting trick to consider for other shots but for this one I find it take a lot away from your friends look. If you have another chance, experiment with the same interesting angles but isolate your subject from further distraction and I think the shot will be all the more impressive.
Nonetheless this is a nice shot and one which you can further experiment with!
