close-ups like this one are a difficult job. On your picture only a small section appears to have 'acceptable' sharpness ... the kink of the proboscis and a part of the compound eye. This is not enough to obtain a good evaluation. The aperture of f/5.6 is probably too 'large'. Clearly, if you work without a tripod, you will need short exposure times. But I think that 1/150 would have been sufficient concomitantly achieving a smaller aperture.
Point of view and composition are good. Background noise is a little bit high.
I hope that my comments may help!
Best wishes, Peter
P.S. I tried a workshop to improve the picture a little. I hope that you will like the result!
