don't like the choice of selective desat here - the butterfly and flower are fantastic and the grey background really makes this one go flat in my opinion
nice background selective desaturation except for the small desaturated flower in front in the focal plane over the purple flower in back OOF seem to be switched for desat.
I really don't like butterflies, but this is a good shot and I certainly won't hold my fears against your score. Lol. I like the color contrasts, clarity and composition. Good luck in the challenge.
Beuatiful butterfly here, but I don't like the selective desat. I don't think it adds to the photo. The flutterby is already the main subject you didn't need to emphasize it by the PP.
