The underside is lovely as everyone has said.
Do you think the hardest part of trek ships is doing a side view.
I've tried to sketch out Galaxy class designs with raised nacelles, and the supports always look to chuncky. I like raised nacelles, but in some respects lowered ENT-D versions seem more fluid.
Have you tried sharply angled lines atop nacelle supports to either side to make struts look more rakish than they actually are?
