@AxleMC131:
That Buffalo Mk. II looks pretty good.
Took your idea of a jetliner-in-space and reworked it a bit.




Basically, what I did here was that I unified the shapes a bit, to give it more of a look of a reasonably atmospheric-capable craft. I know that in the SS universe that isn't required (they have anti-grav and presumably Shields allow for atmospheric reentry) but it fits with the jetliner feel.
I also hid more of the mechanical greebles. Commercial / Tourist vessels IRL go to much more trouble to hide such things than military vessels do, and that fits David's conceptual approach to those kinds of ships, too (see the shuttles).
While the wheel was a cute idea, it doesn't really fit well with the SS level of technology. There aren't hab-wheels on the other ships or other obvious aids to create artificial gravity, because they have some method of doing that technologically. And the wheel really broke up the flow of the shape as well as making the airliner-like front not really make any sense.
Not so sure about the guns on the sides of the front fuselage; I was thinking that, given the mission of the craft, it'd be best if they were missile launchers to provide support or to fling at enemies while escaping, but I think they'll disrupt the shape a bit. That's the problem with ship concepts like this; they can turn into a greeble-mess simply from having guns on them. Might be better to make the launchers a fixed part of the ship itself, ala the Onslaught's Thermal Guns, to hide them and keep the shape clean.
