Trim the white and get rid of the "warm" pinwheels. Swap out the warm ones--orange and red--for something else. You've mixed warm colors with the cool bright pinks and I think that's part of it.
Oh, what if you framed your ballerina after you trim off some white, then put the pinwheels on minus the orange and red ones?
Edited....your pinwheel background is also coming off as yellow or maybe it's a beige. That too may throw you off.
