This is a fabulous idea for the challenge. This is just my opinion but I think the focus should have been on the bubble. I think your score would have been much higher.
what a beautiful idea! I agree with Jayson, the colors are exhellent, and the slight diagonal line of the flower makes the composition just perfect. what a light and dreamy and fragile feeling the photo gives!:)
A wonderful picture. I really like the idea here. Very simplistic style, yet the "bubble" creates a lot of interest. Terrific blue background. Interesting, curious how you did it.
