Great motion, great lines and contrast. Looks like the guy is riding his skateboard in a parking garage or something. The fact that his tounge is sticking out makes such a difference. This is concentration....he's doing something that very few people master.
Thanks for the comment. This kid was kind of crazy... its about a straight 10 foot drop and a 2 foot ollie over the barrier and he just went right for it. Gotta give it up for kids willing to risk it for your lens.
