I have been doing some experimentation with different lighting techniques since getting my Flash Waves radio triggers. Here are a few macro samples of flora from around my yard.
Getting the flash (or flashes) off the camera certainly lets you control your lighting much better.
Dual FL-36 flashes. Shoot through umbrella to the right about 4 feet from the subject, with flash on full power.
Another FL-36 strobe with home made snoot and grid in close slightly to the left set to 1/32 power to make the purple leaf stand out from the background. Without this it was rather dull.
