Setting aside your question is there a nicer TOS Romulan ship out there? I'm curious what you would consider to be the "TOS era design language" because your Romulan bird of prey seems to color outside the lines of that standard. The ships we saw on Star Trek were simple geometric shapes that were easy for VFX modelers to build back in the 1960s. Your BOP features tapered warp nacelles (or whatever the Romulan equivalent FTL technology was back then) and aerodynamic struts that blend smoothly into the main hull. Your BOP also sports all sorts of lovely little details that would never have been placed on a physical studio miniature used for TOS, simply because no one would ever see them on the blurry TV signals broadcast back then. And apart from those constraints defined by technology, there's also the look you've achieved here. This is sleek, streamlined, and elegant. I would totally buy this as the latest in Romulan war technology... if this had appeared in an episode of Star Trek: Enterprise. (Or maybe even in an episode of Strange New Worlds, if they figure out a way around some thorny canon issues!) But does this fit in with the established TOS aesthetic?
