Yup, because it shouldn’t be literally Naga/drake.
Naga - source of tri-hull idea.
Drake - side angles and bridge.
Jackdaw - dat strange antennas.
All other is from my head and from “how the spaceship should look for this or other purpose”.
Air intakes on front - just because I like how it looks, also seen on some ships.
Insanely huge engine exhaust - I imagined, that the ship used engines from a higher-level ship. (innate reduction to AB requirements, hehe).
Like this.
