I like it both ways. With the circles is much more fun. As others have suggested, try rearranging them for more balance and try overlapping a few of them for more depth. I would also trying a couple right on the edge of the quilt by folding them just to see what it looks like and how about folding a few right around to the back of the quilt so you see some from both sides! ooooh! Love the strata style of the top. It is going to be so cool when Finished.
