seems to me that this is the wrong way around: out to be legs on left, ball on right. Light on front of legs, not back. pink, blue, red and green are not commonly found together - I think that the pink and red clash. Otherwiose, nice DoF, good idea.
I know there are some people here at DPC that will score this low as they won't feel it fits the challenge, however, I disagree. This is a nice composition and the colors are spot on, at least they are on my monitor. Good job and nice photo and I wish you well in the scoring.
