I agree with @Jill_C . Cropping will also remove the large white spot which might have been clipped highlights.

This is what you're competing with in Stock.

It helps to compare your best work with current inventory to see if it's something Stock needs. 

Good luck.

There is noise in the background, but that is not really too strong. 

I think it's the overall concept, with this little butterfly, and then covered by the flower.
