When TrashMan was doing his HiPoly Demon (which got trashed during some HD problems, IIRC), I had suggested doing some cresting on the head, and some overhang at the bottom of each side panel, with some red glow from the hidden bit.
Head, side profile: standard on left with suggested alteration, end result on right

Main body, front profile, intended as the widest points on the ship, which meet together as the spoiler on top:
Full arc (top to bottom) on left, closeup of altered sections on right.

As you can see, the changes are nearly opposites of each other, because of their placement on the ship.
