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!
