Nice shot! :) Couple of nitpicks.. for the challenge at hand it would've been best you probably used a yellow pastel fabric instead of pink, since it now competes with the yellows of the flowers. Might lose points for that but I really like the colors. And the tree branch near the top left.
This is a great location for this challenge and this is a decent shot! It would have been nice if the blanket this person is holding would have been yellow to complement the nice yellow foreground. Maybe even get her to wear some more yellow! also the trees in the sky dont really add much they just draw your eye away from the subject. They arent really needed. I find the best images are when the distractions are minimized.
