Overall, you have a good eye for compostion. There will always be some difference of opinion, but generally, I think they all work. They also look sharp on the small versions, which is always the key to a good macro shot. One thing I will say though, is watch you don't overdo do it in post porocessing. One or two look a little oversharpened and some of the saturation is a little high. Sometimes you want the oversaturated look for artistic purposes, but often less is more, particularly in natural history. I find sometimes that a contrast boost (using curves) gives too much saturation and have to tone that down afterwards.
