One thing I'd like to see corrected is the explosion of the final two TIE fighters in the asteroid trench as the Millenium Falcon escapes them. It's always appeared to me as a badly composited explosion effect. The 'fireballs' (or whatever you want to call them) seem very floaty and don't seem to match well with the camera movement. This may be a hard thing to fix, but would make the explosions seem more real.
DE was doing some great things with his edit. I highly recommend taking a look through his thread again, it may spark some more suggestions and debate.
