You know what'd really ice this cake?
Pennants and insignia
Couple of tiny "USS TITAN NCC-76542"s on the nacelles, maybe some thin red lines around the impulse engines and shuttlebays, perhaps a starfleet arrowhead pennant with those red lines behind it (with the name + reg text inside) along the length of the secondary hull, maybe on the nacelles...
That, and a couple of dimmed out window's, and she'd be fully pimped
