Looks very nice. Minor complaint from me about the spikes (antennas) and the engine, but otherwise a very fine looking ship. I say do it, get it ingame.
The antennas should be removed. I see no need for such big antennas on the ship, they look too fragile. Maybe a small antenna could be added elsewhere though.
The engine seems very small, based on the BS engine, mh? I'd go for something a bit bigger. Doesn't necessarly have to be round engines, but I'd prefer that, because iRP it's an old cruiser model made by the Hessians, and the BS is a new ship, just developed recently. If you still want to keep this kind of engine, maybe put 4 of those on there and make the engine a bit broader.
I want to see it ingame, just as much as I wish for Luis' Vidar model to be placed ingame finally! ;D
I think you're talking about the exhaust.
I'm going to add back (sort of) the first exhaust idea I had, along with these.
