I always find these interesting to look at....they're so complex. The DOF to the background is very nice. But IMO I think the 2nd dandelion is competing for center stage here. I think if you would have shifted over to the righ slightly whereas only a portion of the 2nd was shoing would have been nicer.
I like the DOF here - unusual to see more than one dandelion per frame, but adds some interesting depth. I feel like the crop might be too tight on the bottom.
Dandelions - man, I haven't ever seen that before. ;o) Just kidding... it's a beautiful subject well photographed. the focus is a bit narrow, but I love the composition.
I love the focus on the center of the first dandilion but I think maybe extending it a bit father would have helped. So much of this picture is out of focus that it makes me wonder why large parts of the image are even included.
