Suggestions for what to fix? That's easy. The lasers during the Battle of Yavin!

There are many desaturated laser blasts during this whole sequence, and some also that are just the wrong colour altogether (blue exterior with a green core, instead of green exterior with a yellow core). These are still present in the latest workprint, and with everything else looking amazing they stand out as wrong all the more. I'm actually surprised no one else has pointed them out.

This partially falls under colour correction, so having reference frames with lasers in them would help, but even in the GOUT their hue and saturation level looks good, so you wouldn't have to wait to be able to take care of them.
