Personally I think you are doing a fantastic job and the extent of work that you are undertaking clearly shows. That said there's always room for improvement and I agree which the remarks made by Sober about lengthening the release of the rocket. We see Supes throw it into space only for it to explode immediately. The idea of using footage from Supes IV could prove valuable.

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.
