No. 1 is my pick, def. a stud-ly shot! Those lactic acid filled thighs looked like he just finished sprint intervals , definitely slow twitch muscles. But the blue liquid filled bottle in No. 1 does distract me a little bit. Wonder what No. 3 would look like if it was in color.
The lighting is very cool. However, the photos look too red to me. Can you add some yellow back to them so the skin isn't so magenta? Also, I think some detail shots would be great compliments to the portraits and action.
