This doesn't really emphasize the roundness; it doesn't fit in; and I'm at a loss as what to do next. Besides I don't think those large circles will be all that easy to sew.
What if I emphasize the yellows by outlining them with black stitching?
This doesn't appeal to me; I don't think it adds to the design.
This does add to the design; I like it.

I think I've taken this idea as far as it wants to go. Doing white spirals in the white areas would be overkill.
For the white areas I think a filler design such as stippling or pebbling would provide some contrast and work best.
