Think the futuristic ship design thing was kind of was already broken by ENTERPRISE, although it's interiors didn't quite look as 'comfy' as the later Enterprises.
Apart from the Nacelles the exterior largely just seems to be taken from the Akira class which appeared in First Contact and a few DS9s and Voyagers.
Funny thing is the Shenzou, Discovery etc. kind of look fine as descendants of the NX-01 but don't quite fit as contemporary with the TV show constitution class.
