Hey! Another butterfly shot. I gave this a 6 when I came through originally. 6 to me is a solid shot so I think you are a bit underrated.
I think what hurt you the most is the razor thin DOF. It was a real balancing act in this challenge. The best shots managed to keep most of the subject in focus while having the background still all "bokehed up". When I took my shots, I would find a subject and then fire off with my finger on the dial for changing the aperture. I started at 4 and then would work my way up in maybe 2/3rd steps to about 8. Then I'd sort it out later.
Colors and composition are nice. What IS in focus is sharp and nicely done. The flowers are just a bit blown.
