It looks like there's something on/under the right side of the saucer.
I wonder if there are any other views of this completely brand new, original style of ship.
Here's a slightly cleaner pic.
Since symmetry is so common among Federation ship designs, that starboard under-saucer projection would have to be matched with a similar port-side projection as well.
If you care to retcon this "Galaxy 666" image into the TREK Universe, that is.
For sake of argument, I would take the image with a grain of salt, and not follow it too faithfully. It could work, in some distorted fashion, as a pre-pre-TOS / post-ENT design. I would be neat to see a "neck-less" design, with the secondary hull blending in with the lower saucer and dishes extending out to port and starboard. Or it would be interesting if there were a neck-and-secondary-hull arrangement, but the saucer's underside had multiple domes or other structures a la Stargazer.
The weird piping/latticework joining the nacelles directly looks weird, even weirder that the Reliant's photon torpedo "roll bar" from TMP2. I have no idea what function this would serve in-Universe, unless the structure houses impulse engines or something.
I think the idea of a distorted "anthill" bridge dome is a neat one. There are mildly interesting design possibilities if you distort different aspects of the TOS-era saucer. (Example: imagine a
Baton Rouge or Kelvin-style saucer, but with the bridge-structure replaced with the top of a
Daedalus-style sphere, like a super-pregnant "anthill". Now imagine the saucer underside without the TOS-style lower vortex, but with Stargazer-style under-domes.
