I think this is a great capture. To be helpful, I want to suggest that you crop in closer to the moth and the flower so they become the focal point. The design of the flower stands out great and would make a beautiful close up, especially with the moth in the center with it's markings and colors showing so well.
Very good entry for the contest. Excellent close up of this lovely Sunflower with the moth resting in the centre. Very good lighting and focus showing great detail. Great composition. Good luck in the contest. Suzanne
This is a nice nature shot, I love sunflowers, this is well focused, the image is clear, exposure is well managed, the colors and tones appear natural. Tiny moth shows well in the center of the sunflower. Well composed giving a sense of this location, well presented!
