Belfrybat, I actually like those colors together. But Iceblossom is right, if the red print gets chopped into smaller pieces to focus on one of the other colors besides red, I suspect it will give you a scrappier impact. All the print fabrics in red and green play well with the other colors. I've never done one of those quilts so Iceblossom's input is valuable. Didn't Bonnie Hunter say to avoid big prints as they may change the look of the quilt? Sounds to me like small pieces are coming. You could always wait and see what gets paired up with the reds and the sizes and then decide if you want to keep the big print red.
Wishfulthinking, if you want pink, you should use pink if it plays well with the other colors you've picked. It's your quilt :-)
