Perhaps not what I would expect to see if I went to an exhibition of portraits! As far as the photo goes, the colour combination of red and green is good, and the diagonal nature of the composition works. The focus is slightly soft - a very slightly deeper depth of field might have helped. I find the black and red stripiness of the background slightly off-putting.
Gosh I love macros...esp. of insects! But I wasn't expecting this subject in this challenge. A pleasant suprise, I guess! Nice color tones and subject clarity. *6*
