Re: 22nd century star clipper...
I'm not sure I'm familiar with Masao's work but I'll check it out.
This is Masao's Starfleet Museum
website. I particularly like his 22nd century ships (on both sides) set during the Earth/Romulan war. I think his Earth Powhowtan
-class ships are particularly cool as well as his later Starfleet Predator
