"Edit! Well I now know It's a girl!!! Thanks to *BFGL For letting me know! It's a Black Swallowtail and the female has the blue bits, so Yay! congratulations - it's a girl. Posh name is Papilio polyxenes."
Writing a critique is really demanding this time. I am supposed to write what I like about the photo and what needs improving. But it's hard to criticize something which is an ideal shot. In front of my eyes I have such a lovely and beautiful creature... When I noticed this picture, I immediately clicked to see a more detailed version. Butterflies are very fragile, specially their wings, so it's hard to take a picture of such a beautiful one. I like everything in this photo, the colours, contrast, pose of the butterfly... there is nothing which needed improving in my opinion this time. My sincere congratulations!
