Interesting. I like this shot for its technical/graphic aspects more than the artistic/aesthetic. The black and white is nice. So is the composition, lighting, and contrast. I would also prefer the focus to be a little more even - without the shadowy area on the bottom half of the lens. Nice diagonal.
This was a tough topic, and I think that the voters really appreciated creativity just because they had such a hard time coming up with any ideas themselves. Technically, this is good and probably should've scored a bit higher. I think that the idea is as important as the ability. Your ability is good which puts you in about the same spot as a lot of us... just waiting on creativity to strike :)
You quiz my geometry skills here perhaps? I like how the inner circle is framed by the outer circle here. The creative focus is really intriquing and tends to imply that pi requires exactitude.
I'll assume this is one of the shots that is too smart for me :) I like the concept here. I don't like the focus very much - could have liked to see all the the drawing inside the lens in focus. = 5
