As said, this looks a pretty tricky object to scan. Probably not the best choice for your first scan.
I would try something like a clay or porcelain model to begin with, you should see much better results.
When you need to move on to more difficult objects with dark or shiny areas, you should try experimenting with either water colour paint or chalk spray.
I use chalk spray which works great.
It can take a bit of work to get good results with some items but others will scan great straight off the bat.
Take a look at the "post your scans here" thread and you'll get an idea of what this scanner can do.
It's a fantastic bit of kit once you learn the ropes with it !
