Interesting. I'd have imagined the pirate ship being slightly less spread out, more aerodynamic, less hull area to damage in a running warp-firefight. Such as a Whorfin-Class
Note's from KnightVision3D were along the lines of the freighter is meant to resemble different parts of other ships. The hammerhead being Cardassian, the dorsal fin being Romulan, and some from species we havent encountered. Very much a kitbash by design, and meant to feel heavy.
