For me this is a beautiful capture of a Poppy - the bee adds that little extra interest!
Be careful to keep the main subject totally in frame (I see you've just touched the edge with the petal on the left), unless you are going to crop even closer to the center. It's really difficult to capture some flowers outside, especially Poppies which wave around in the breeze - you've done really well!
With my mod all I've done is crop a little closer to the bee (I may have gone closer, but because you've had to resize for upload it became a little pixellated). Well worth experimenting with different crops and seeing which you prefer.
Edit: Mmmm. I'm not really happy with the quality of the image now I've uploaded it (I wish there was some way of deleting it), but it does give you any idea of how I might have cropped it.
