Zab, you are a powerpoint expert! Joking... Nothing better than a drawing to explain!
@Tags, yes you will need more light coming from both front side of your mini, as drawn by Zab, it can be artificial light sources, you need to fill your shadows, which means to avoid too dark (black) area on your mini, but you also need to avoid hotspot, where it is too bright and simply white. So you need good camera set up and good lighting with more than one source. One quick tips, depending where you live and actual weather, but taking some shots outside with the sun prove to be quite effective!
You can also go to the painting section with the
tutorial. i believe that you will find resources... Then if you realyl want to go even further you have miniature mentor who did a miniature photography tutorial, but it requires a bit more patience (to set up everything and get it right) and money (buy extra light sources), but it is a nice tutorial in the understanding of photographing minis.
