I wonder how you would handle the Orion pirate ship...
I'd have to really study it. In my opinion you can't simply take a roughly drawn animation design and translate directly into the "real" world and expect it to look credible. You have to adapt and tweak it. With the TAS shuttlecraft I strived to retain the essential concept and general overall look while massaging the designs into something more believable in appearance and size.
Sort of like what they did with remastered TOS I guess, as in making some of the cargo ships/freighters look like their TAS designs.
Nice work on these, though Uhura looks a bit flat-chested in the skin tight spacesuit.
