You have some beautiful layouts there. I love the colors!!
I like2,5, and6---#2 is my fav. I think the sunflowers would be nice in #2 if you put a few more blocks with SFs in the bottom of the swirly circle part and in the corners of the quilt top,----and maybe? one in each side--- but maybe leave them out of the 4 center blocks.Clear as mud???
Whatever you decide, it's going to be a wonderful quilt.Looking forward to seeing the finished project.
