After learning some new tricks to make curved surfaces I rebuilt the Hephaestus' saucer, I really liked the improvement and the way the impulse engines look now.
I also redid the side pylons.
I think the saucer looks a better with the rounded sides. The underside has a pair of landing repulsors to facilitate soft landing and takeoff, and the dark areas are landing surfaces.
BTW, where are the controls for camera focal length in 2.65?
