Some of my macro's
The first 6 shots are too small to be able to tell much at all. The last two I quite like, using available light (rather than flash) gives a nice soft quality to the shots.
In general, if you want detailed C&C regarding your photos, it's best to post just one or two.
What aspect of your macro photography were you looking to improve ?
