I am absolutely no expert, but I think we all get ideas from each other so I'll throw in an opinion. I really like your floral base fabric but I wouldn't add any more different colors. I would use the maroon, peach, and dark green again to tie them together. All but one of your stars have white backgrounds so I would do a couple of others with a dark background. We aren't even half way yet so we all have plenty of time to make adjustments.
PS, I really like how you did the first star. Somehow didn't notice that the first time.
