Yet another mini ship. This one is basically a mobile prison. It can't hold as many prisoners as a regular non-moving prison but it's great for transporting large numbers of prisoners from planet to planet.
Looks good. My only comment would be that it looks a bit too stylized to be a prison ship. I think of a prison ship more as being simple and nondescript, this looks more like a cruiser of some exotic alien race. Just my opinion. I like the design and the angles you worked into it though.
