The upper blurry part is too much and distracting in my opinion, it takes my eye away from the flower below. I think the cropping on the right side is a bit too tight.
This shot has tons of potential. First off, always try to use the full 640px composition that is offered here. Second, the right hand edges of the petals need to be included in the frame. I do really like the colors here, as well as the depth of field that you acheived.
IMHO I might've tried a little higher angle just to get a little more detail in the center of the flower. Still a really nice shot though, love the colors
