Here are a few I've put together with Vance's toolkits, just for my enjoyment, I endeavored to make stuff look even. But I'm not as good as Vance...lol.
The Oracle Class Listening Post, a quick outpost thats cobbled together with premade structure and parts. Something that Starfleet Intel can assemble at a moments notice, a spy station of sorts.
And a the Argus Class Cruiser and Dreadnaught. I wanted to make a fast looking Cruiser with the shovel style saucer section. Kind of a quick strike craft.
