Cartwheel

I like the colors of this one - very muted but not dull.
I think the cropping should be different though - the light on the side and the celing above distract from the subject and make it look less clean. I would recommend giving a little more space to the right of the wheel - maybe even roll it closer to the light to include that without the awkward visual jump between the two.

oy - did any of that make sense?
