Hi Randy. I really like the diagonal of the leaf edge as well as that of the butterfly! Good sharpness and lighting and the artificial background worked very well here. You could make the antennas "appear" a little sharper by zooming in to about 200% and then carefully cloning away the OOF fuzzy edges. This is very nicely done!
Excellent composition, love the stance. As expected exposure is just about perfectomondo! I am curious about the antennae, one dark the other pale, are the inner aspects paler, I presume so - never noticed it in other species before. A very well prepared image, I like the background it works well. I know there is little that can be done now but I wonder if the background had a higher contend of the emerald green it would lift the butterfly a little.
One tiny criticism, if I look carefully I am detecting a few small dark splodges in the background.
