Add some bracing at the "elbow" where the wing meets the engine pod. Currently, it's at possibly the worst angle from a structural viewpoint, especially for an engine. One misfire, and that pod breaks off. Also, you might want to move the missile pods to the center of the vessel, since it's kinda empty over there.
Nice ship, looks like a next-gen Starfury from B5. Thunderbolts, were they called?
