"I do agree to an extent about weathering and panel lines. But you sort of HAVE to do something to make it look more interesting."
Hmm...I always felt the design to be so timeless and still light-years ahead of our time that there wasn't really any need to make it look different.
What I really would consider to be "interesting" would be a presentation of a USS Enterprise
in dry-dock configuration, i.e. with all the exterior hatches extended / opened for repair and maintenance (as this is something I've never seen done before).
