Now that I think about it, the only thing (or at least, the first thing) I’d really want to change (if I had the software, time, or know-how to do such things) is the colors. Teal and orange was prominent in many scenes (as with most modern movies), which was especially noticeable upon second viewing. Unless my eyes are being weird and I’m seeing things that aren’t there (which has happened before).
Your eyes might be weird. Colors are pretty natural throughout. Didn’t notice an orange shift anywhere, though the First Order interiors often had a teal look due to the lighting. If you want you could pretty easily remove that, but I’m not sure why. There’s nothing inherently wrong with teal and orange.
I swear the stars behind the crawl looked blue. The rest of the stars looked fine to me, but the first stars just looked blue to me.
It still isn’t inherently bad, in fact I think it looks pretty good. I’d just want it to better fit the OT. It really is, for the most part, the First Order interiors, like you said. This is about what I had in mind (taken from a youtube video I found):
