Thanks for the comments, giantacroyear. My current project is the Boreas Gunship that can be found here:

After that, I have the rough shape for perhaps a corvette class or a cruise ship. I haven't decided on the details yet. I also have a rough one-man starfighter in the works as well. I need to finish the Boreas Gunship before I move on to those other projects.
