Subtle flash work, which from me is always a compliment! Your focus plane was just right, sharp from tip to tip of wing. Sharp, well exposed. Nice angle in frame.
I might try a version with the lower right corner vignetted just a bit to aid in separating the butterfly from that area.
Save for the right wing's tail this specimen is in perfect condition! Some areas of the BG could be smoothed out a bit (e.g. close to right wing tip)...was there some work done there? Good stuff overall!!
HI Allen....very nice work getting such nice focus throughout. I would brighten the yellows in the wings just a bit and take down the saturation and brightness of the flowers. I also agree with darkening the leaf in the right corner
