I'm pretty stoked about this one. I've been trying to figure this one out for a long time, and despite the flags being kinda big for the dorsal and ventral fins that hold the engines i think this looks pretty good.
Update: I put a yellow technic bushing in between the fins to fill in the empty space.
About this creation
another shot of the new version. I added a little more structure below the front
the old version
This shot shows the slenderness of the craft. The Alliance stripped down and modified the Rendili Dreadnaughts they acquired so they would be faster and require less crew
