You seem to have a variety of fabric types mixed in there, cotton, satin and flannel. I am not sure that they will all play nicely together in a quilt. Satin will not press well, nor will it give you a nice 1/4" seam if paired with bulky flannel, the turn of cloth for each is very different.
I would try a few seams and see how it works.
I am not a pinks and greys person. You have one other print with each colour except the yellow. Do you have another print with some yellow in it and one of the other colours? I made an Around the World quilt 20+ years ago with one colour that really popped. I have always thought it looked a bit off.
