SeventhAve said to me he loves this pic so much, what is it do you think?
Over the shoulder poses have always been underrated in my opinion. Not only can they show off really good angles and profiles, but they often have a sensual look to them. While I try to be wary of the pitfalls of armchair psychology, especially with little evidence to back it up, I also think over the shoulder poses hit on something subconscious that often makes people like them. That's because if you think about it anybody that does that is taking extra special effort to look at somebody. When that somebody is an attractive women and she's going through that effort to look at you, well then that can make bells start ringing in one's head.
To add about your particular photo along with the above I think the lighting was close to perfect on it, and I love the casual and easy going vibe you are giving off while still being sexy doing it. Part of that might even be that while you are sexy you are doing it in a way that's not meant to be. It's closer to looking like an normal everyday event caught on camera rather than a pose that's blatantly done for the purpose of being on film. Not that there is anything wrong with those either.
At least that's my :2 cents: about it. Although I'm sure I've overthought it.
