Lord of the Ring Flash

I just got a cheap ring flash to use with the macro lens for my Nikon D80. The ring flash will let me get closer to tiny subjects. Until now I have been using the built in speedlight on the camera, the problem with that is that I can only get so close before the shadow of the lens barrel intrudes into the shot. I just started experimenting with the flash yesterday, already it seems like a big improvement. There are probably a lot of tricks of the trade I need to learn to get consistently good bug shots. Here are some of yesterday's results, it's best to click on them to see the detail.
