Sorry about that, the trouble is...I'm not really that good at macro either to give proper informed advice lol. But the general rules for me would be, the bug should stand out from the surroundings so that the background and foreground should be clutter free and OOF to make the bug pop.
But for example number 4 the house fly, thats the closest to what I would say works as a good macro for bug photography. Nice OOF bakground, nice light on the main subject and the DOF is pretty good BUT you have chopped the feet off at the bottom.
Most of the others you seem to just be looking down on the subjects which doesn't really show them off very well.
The best advice I can really give is check out Messiah Khans macro stuff, its top notch and explains what I'm trying to say without me bumbling on lol
