Nice concept! I did not vote on the nudes, and just getting to view them for the first time. A fun shot! Sheds some light on Surf Naked. I think I saw that on a t-shirt somewhere!
Doesn't really work for me. Feels quite haphazzard/ last minute. The apparent on camera flash or front lighting doesn't lend itself to appealingly lit results. Low score.
Good pose and concept. The flash lighting and the resulting red-eye and flat detail make it look rather like a snapshot. Also, I would prefer that his feet weren't cut off.
Looks a bit too much like a snapshot for my taste, and onboard flash is usually not a great source of light. You could have removed the red eyes caused by the flash in PS. The background isn't too great... try to prevent objects such as trees growing from your subjects!
funny pose, but that's about all - the lighting seemingly from a direct flash isn't very attractive or flattering., His pose is sudden and awkward. Both these things together look like a snapshot.
Kind of a middle of the road image, nit great but also not bad.
Okay, he is nude, diagonal composition with the surf desk would be fine, but there are a few issues I would like to mention: You have cut off his feet, and the lighting isn't that well either. Due to the flash you lost colour shades and the red-eye effect in his eyes is harsh (as it's a member's challenge, you could have got rid of them using separate RGB layers and delete the red area on the red layer). It rather looks like a snapshot, than a conscious work, sorry. Next time, try to use diffused lights, and check that everything important is on the photo.
