Came across these randomly on Facebook. I've never seen them before. Apparently, they're from the instruction manual of a Bandai model kit.
I like the top one (which admittedly looks a lot more like a re-imagined NCC-1701 than a prequel ship), second one's okay and the 3-nacelled ringship is just bizarro.
