I like that all-over design, but if you are more comfortable working in small areas instead of a design over the entire quilt top, maybe something like this would work.
SID between all the blocks with MonoPoly to stabilize the quilt, then quilt a free-form funky flower in each block.
I would just start in the middle with the swirl then four petal shapes, then fill out to the corners with a bracket/leafy shape using just one continuous line for each block.
Very free-form and organic and forgiving!
