Lest it get buried by the debate over the canyon collision sequence -- and for my two cents, I like Ady's original pass at it myself -- I thought I'd reiterate that there's a minor technical error at the 2:30 mark, just as the spinning TIE Fighter explodes: the edge of the matte for the explosion effect is visible against the star field. Looks to me like some opacity tweaking would solve the problem.
Here's an annotated screenshot. It's harder to see when it isn't in motion, so I cranked up the brightness to make it easier to see what I'm talking about (here's hoping this works; never posted an image here before):
The edge is visible for roughly 1-1.5 seconds.
Ady, I hope this is a help to you, and I congratulate and commend you on your continued, mind-boggling achievements with the Revisited series.
EDIT: Arrgh. Here's a direct link to the image instead: http://imgur.com/Xe8ESJ3
Can anybody tell me how to insert an image here?
