I love the quilt and the colors and the over all bright, airy, light look. It looks so very modern. So many modern quilts just don't need the borders we traditionally put on most of our quilts. So having said that....When I can't decide on borders, I lay the fabric out on one side as I think I want it and take a picture. Then I look at the picture. Lots of time I am surprised at the changes in the look of the quilt. I don't cut any fabric until I am absolutely sure about what I want to do. What you have described, seems to be very busy. I'd want to see a picture before I make any real comment.
Edited to add: Looking at the quilt again, I think I would add a white border on the other two sides to float all the darker pieces on the edge and then whatever, if any, borders you want to add.
