I loved this first cut.
Ignoring the abrupt sound cuts and small errors (I hear the cut scene of the villains in the destroyed temple during the Sabine and Ahsoka one after the reunion), I feel that as a first act the rhythm flows well and that it is a model introduction to a film, without a rushed pace but also feeling light and pleasant.
I also really like how you have resolved Sabine’s injury, I think it looks wonderfully well and that it can be understood that she has been injured without it being something as serious as what is seen in the series.
I haven’t been able to see the clip with the two medbay scenes combined, but it also seems like a great idea to me.
As a silly detail, I feel that the cut of the shot in which the New Republic cruiser appears is very noticeable
after the opening crawl. I suppose you will polish these details tho.
On the other hand, have you decided 100% to make just one movie for the entire season? I really felt this sixth episode like the beginning of a second part of something, with Ahsoka’s arc quite closed in the previous one. The second film may be considerably shorter than the first, but narratively it suits me better divided into two films.
