I like the composition - but I wonder.
I assume this was with the canon 100mm macro and the 30D - but as for settings what did you use for apature, ISO and shutter speed?
hmm your aperture is way too low for macro to work well - you really want something greater than f8 and many here seem to use f13 as a good place to set the aperture for macro insects.
This will give you a greater depth of field thus letting you get more of the insect in focus - and should be doable with the 100macro handheld - boost your ISO up to something like 400 or even 800 to keep the shutter speed up.
Thanks for the tip. Yes, I'm slowly learning. I'm trying to avoid upping the ISO too much ... maybe I just need to boost my fill-light a little to be able to keep my shutter speed up (does anyone want to donate a ring-light to my favorite charity? )?
