Those sound like sensible cuts. There was a lot to like in Andor epsidoes 1-3 but the pacing did feel a bit off to me. It sounds like your thoughts have tallied with my own in terms of what could be edited to improve it. The Timm scenes and the chap who talks to Stellan Skarsgard on the shuttle were both unStar Warsy and uninteresting, I also suspect the childhood tribal flashbacks will work better in abridged form (or perhaps even removed entirely, although I did enjoy that shot of the damaged vessel streaking across the sky).
I’ll look forward to seeing this progress.
