Concept is a definite 10. Composition is a 10. Execution - well, it failed spectacularly. Hell of an idea, but the ragged center with the incomplete white just ruins the whole thing. Sorry.
Had to give this a 1 for DNMC. Normally I would -3 but since in this case, the theme was a hard and fast rule totally within the control of the photographer, I'm forced to be a little more harsh.
