More "macro" attempts

These are about as close to macro as I can get for now. Taken with my 75-300mm lens. I think these are about as sharp as I can get with this lens.

Personally I digg, 1 and 7

These definitely turned out better than my last attempts. I actually got the bugs in focus on a large amount of shots I took rather than last time.

I really like the first one

First one for me

Seems like people like the first shot. It was actually vertical, but I flipped it horizontally for some reason and didn't change it. Any crops that would make anything better? Tips for next time?

This was at Virginia Tech's Horticulture Gardens so I can go over there pretty much any time I want.

I like 1 and 3. I am certainly not one to give advice, but to me a couple seemed a bit noisy (5 mostly)

5 is a 100% crop. The rest of the picture wasn't very interesting. Not really sure why it was so noisy.

The last one is very good.
