Michelle, This seems like a very interesting subject... however, the pixelation in the image makes it very hard to critique. Was this originally a large image that was severly cropped? Ok, well for what I can see, the light seems very good, and the exposure seems to be right there. There is true black in the flower as well as hightlights which is not an easy thing to accomplish. The muted green in the center of the flower is lovely, as well. The composition is very nice, however, the background is distracting, and I would suggest an even tighter crop (not of this image, a re-shoot would be needed) to eliminate the darker "rocks" and the "line" rising out of the top of the flower. This is such a unique subject (one does not usually see black flowers), please try to re-shoot. Set the camera on macro mode, set the camera 10 or so inches away from the flower on a tripod and let it rip... but most of all... have fun!
