Not everyone likes blur, I know. And for those who do, it often needs to be done right. But I don't really take blurry shots to make great photos - I take them for how they shift my perception of ordinary things. Normally, it's about colour and line - blur accentuates the blobs of light and shadow revealing forms in scenes you may not have otherwise noticed. Like a big Rorshach. But this shot is different still - it's about legs.
Check out the girl in the top left. She looks so...balanced. Or ready. Or something. The blur and cross processing allow the light to wrap around her form, and highlight how symmetrical her legs are, just how perfectly legs are designed for balance.
I burned the left of the shot to minimize the washout - just duplicated the layer, set it to Colour Burn, then used a Black to Transparent gradient to selectively reveal it over the initial layer.
