Great image. I love the tones of his face, and the crispness of the water droplets. Not so fond of the darker areas - a more even background would have been more pleasing to me.
I am not particularly keen on the vignetting; it might suit a more formal portrait, but to me, not this particular shot. You clearly have skill with the camera - your focus is sharp, and importantly, the exposure is good, but this photograph doesn't really work for me. A head and shoulders formal portrait works, but in this candid I feel there needs to be more in order to set the context.
This is a pretty good shot, it shows action and emotion, however for the feel of surfing or just getting out of the water I think the picture needs to be brighter. I think the hazey vignette effect ruins the lighting.
Great shot! Love the vignetting around the surfer and the B&W conversion. One of my fav's of the challenge and one of the best I think in the challenge. Nice work.
