|Critique Club Review:
Lighting, exposure, color, contrast, saturation and hue are all done extremently well. Focus is excellent, and depth of field has been used quite well to isolate distracting background clutter, yet is deep enough to include as much of the flowers as needed.
About the only drawbacks I see here are that the butterfly looks a bit over sharpened. (Though I must confess that it has been too may years since I saw one this close. So it may be accurate.) And the background looks a little grainy. Not bad, but perceptable. A darker backround would have added to this shot. Unfortunately your options were limited there, because of a this being a basic editing challenge.
Overall this is a very good picture and a well deserved score. Good job.
