I agree it's a lot of white. It might be hard to keep clean. Perhaps you could just change the center panel? Say, keep the purple paws on white, but add a black strip between them and the W, then switch the white and purple for the W area?
And maybe on the outer windmills, make the solid square purple and the windmills black and white?
Just some thoughts to add more color and take away some of the white areas.
Hugggggs and good luck!!
