I like the man's arm position, it's quite relaxed and natural. The only problem I see is that the woman is kinda looking at it, thus giving it more attention than needed. Unless...
This is one of those under appreciated shots. I think it deserved a little higher finish in the challenge. The comparison to commenter scores verses the rest tells a story. I think you got digned because of the cross-processed color look. DPC doesn't really go for the Lomo or cross-processing in general.I like it!
maybe this is just a photoshop action but I love the effect. I wish the woman were doing something a little more as a counterpoint to the man's robotic stare and frankenstein arm.
