I see her hand moving fast, so you meet the challenge. I also see the whole picture just a bit blurry and the lighting is uninteresting. nice composition - keep shooting and working on technique. You have a good enough idea here.
I take it that the 'speed' is in her hand movement? It's not realy 'speedy' enough for me in concept. The photo itself might be improved by sharper focus on the face, a more attractive background and less cleavige.
It may be just me, but I dont get it. To me this has nothing to do with speed, unless she's try to break the world record of covering herself in lotion?
There's a difference between 'motion blur in part of a shot to show speed' and 'entire picture blurry,' I'm afraid. Her face, in particular, is disturbingly not-quite-in-focus.
