I'd have liked to work with the physical tails more (the vertical canted fins above the main hull), adding a bit more volume to the lower parts, adding a slight amount of curvature, and moving them further forward. That, I will note right away. But that's me...
The energy wings as far as I can tell however, are done and done. The position they're in is the exact one they're supposed to be in. Bowing the top stabilizer out a little more wouldn't hurt, probably, but it's fine where it is now. And good Lord man, we're NOT going to make it hang off the sides. That's just... wrong.
