The first picture looks good, but the two others could have used a custom white balance setting. It would bring out the colours and texture in a much more extreme way.

As long as you can either get your camera to autofocus on the subject or use manual focus (which can be painfully difficult on small cameras without focus rings) you can pull off some extremely detailed macro shots.
They won't be on par with something done with a Digital SLR and a full macro lens, but you can get closer to the quality then you'd think. 8)
