Except the aesthetic style of ENT and DS9 is quite different from TOS. This is a point you don't seem to understand.I'm not so sure. They had a TOS ship interacting with more realistic and detailed ENT ships in "In a Mirror Darkly, Parts I and II" (ENT) and they all looked like they belonged to the same world (and they have had TOS movie ships interacting with TNG/DS9/VGR ships in the TNG and DS9 TV shows just fine, too).
I tend to think of starships being very futuristic things built in ways far surpassing what we understand today. Hence I think of their hulls generally being like that of jet aircraft or even submarines.
