Excellent composition and texture. It appears about .5 stop underexposed to me as well as just a bt undersaturated. Pretty small nitpicks for a very good image. I'm really glad you angled it and cropped it tight. Very nice work.
For some odd reason when I first saw this I thought of the U.S. olympic team lol. A bit of red, white, and blue along with the rings on the lock. Good shot.
