i like the idea behind the picture, and the bokeh is a really nice effect here, but I would've liked just a slightest bit of sharpness added to the dandelion. overall a really great picture though.
try to put the object more towards one side or the other for a little better composition...love the contrast between the white and the yellows and greens.
Dandelions gone to seed are a bit common here at DPC but this is still a nice photo. I love the background colours. You could have earned a point or two more from me if it weren't so centered. Crop a bit off the left.
