i think it's quite a lovely picture. but i think the image will make a stronger impact if it is square-cropped isolating the main subject which is the butterfly and the flower it's on.
colors wise, i think bringing up the saturation a tad of the flowers would make it "pop" just a little bit more, but try not to get too heavy-handed with the sliders.
subtlety is key.
my humble 2 cents, cheers!
thank you! and thank you for your suggestions and advice, especially "subtlety is key." i fully agree. cheers!
