This is not quite sharp. Perhaps a more accurate focus and smaller DOF would help the flowers to stand out from the background. The again, I do like the way the wider DOF seems to flatten the photo almost to 2d, so I can't agree with me. :)
This would be better if you cropped the trees out. Sorry, but I really like the whimsy of this image and the trees detract a little bit, but that's jmho. I like seeing the colored dots/flowers in the background.
