Now, THIS IS NOT negative criticism.
You've picked a flower that is extremely difficult to photograph and make it look good. The best I've seen have always been straight on to show the pattern of the flower.
By taking this one slightly to the side you lose some of the pattern, not too much mind, but you have cut off bits of the stamen things and the petals aren't all in focus, simply due to the depth of field. The bees in the shot as well fight for attention with the flower and leave the whole composition a bit "busy", no pun intended
I think if you'd waited for the bees to leave it would actually have been better. The other thing which isn't helping is the background foliage on the right, it adds nothing to the shot but because it's brighter does distract a bit.
However, for a macro-ish shot it's sharp enough, exposure is spot on and the colours are great.
