Macro work is fun. I enjoy it quite a bit myself. There are a few elements of great macro photograhpy that I work towards when doing my own images. 1 - Make sure I have a subject that has interesting detail in a macro view. 2 - Choose a composition that makes that detail stand out with a lot of strength. 3 - Don't allow other elements of the photo to distract from my subject (this is the case with any photo.)
The bug in this photo may have some interesting detail on the other side (front view). The surface the bug is resting upon is quite contrasty.
Note: If you request in depth critiques on your photo, the CC members have the option of skipping over photos that have no information provided by the photographer. You should always include your exposure information and a note in the photographer's comments box describing your photo and any intent you may have had.
