I love the way the film opens with Supes in pursuit of the rocket and the transition from the daily planet globe to the red Krypton sun is also a nice touch. The re-cap for the trial of the villains sequence is superb I think you've edited it to just the right length.
With regards to the credits I can understand that you want them to differentiate from official versions since this is your own cut. Taolar suggested adding some noise to the text, which might help them defuse into the background. Ultimately I feel toning down the animation might help. The credits look best when they are simply whooshing across the screen rather than doing all kinds of crazing things.
Keep up the fantastic work I know the finished product will be something to be proud of.
