Nice job. I like the 400m shot best. I think the side lighting adds a dramatic feel that works great. The only thing I would change with that shot is the bare feet. He should be wearing his spikes. Either that, or include the shoes somewhere in the image (for example, in the BG off to the side with a bunch of 1/4" needles scattered on the tartan with a spike wrench). ... With the bare feet & shoes missing, the image seems incomplete. (Just my opinion) I've been a track coach for several years, and an athlete's spikes are where the athlete and the track become one.
