Initial Impression: Nice macro. The colors are a little off-putting, but hey, it's nature, and they're nice and vivid.
Composition: A centered composition works well for macro shots, and this is no exception. Perhaps a more square crop would be more pleasing with the round flower head, but that may just be nit-picking.
Color/Tone: Very vivid colors, even if it's not the most pleasant combination in my eyes. Did you try this as a black & white or duotone? There's plenty of contrast in the photo, and I wonder the caterpillar would have been more camouflaged?
Focus/Exposure: The focus is dead-on, and the depth of field gives the photo an almost 3D quality.
Title: Servicable. It is what it is. Can't find too much fault with it - I have nothing better to suggest.
Meets the Challenge: Yes, I think so. I think I can see what you were going for: the rust of the flower head matching the rust of the caterpillar. I do wonder if black and white would have made it meet the challenge more, though.
Summary: Technically an almost flawless photo. Aesthetically, not the greatest, but certainly not bad.
Aww, how cute! This is a very nice shot, the clarity of the subject and the colors so nice and warm. I'm not really seeing the camouflage angle as the little caterpiller stands out very well there. Also the light on the right side seems a bit overdone for some reason, not sure if you used flash or it was natural light but it detracts away from the overall image to me personally. Again, a great capture, a lovely shot overall. A 7
