While the new missile visuals are beautiful, they're a little weird when a homing missile loses it's target.

Instead of curving around in a circle, they angle around in a really clearly defined octagon. Instead of getting the feeling of it spiraling out of control, it looks like it's intentionally choosing a series of even-spaced 45 degree left turns.
(Which, of course, it is, but I'm not sure that's the visual impression you were intending to give).
When it's doing that, the hard corners on the flame trails make me think of the light-bikes in Tron.
