I'm being brutally honest now, I think the insect could use a bit more sharpness. I'm not saying you should have done better, I know what kind of challenge shooting little critters at short range is.
Then there's those bad-bokeh highlights. They're so bad that they actually work well, and become a feature of the shot. I especially like their colouration. The insect could be as harmless as it wants, those greenish/turquoise highlights make it look extremely nasty.

PS I thought the lack of sharpness might be the result of down-sizing, but trying to look at the bigger picture I only get a site daring me to win a BMW...
