My thoughts, right now, best I can do until my mouse arrives, are as follows:
Give the thing a sloping body, much like some birds, front end being fat and bulbous, the back end dipping into a flatten fanning tail. This allows for a lot of detail to be seen from back on standard camera veiw, which many ships suffer from today. Protrude from the upper section of hull, just before it plummitets into tail, two thick wings, much like the challenger wings. On the end of those, like the firefly, engine pods. These will be ovoids, and decorated in heavy rear facing plat rills.
