It’s really good!
The only issue I sense is with the music cutting from the space battle to Finn and Rey, since there are two similar chords right next to each other. Even though the music overlaying the distant shot of the Oscillator is correct, it feels off in this short scene and the transition just makes it worse. Would it work to use the music from the Ackbar shot and simply extend that through the rest of the scene? The ‘weapon will fire in 2 minutes’ dialogue is of similar length to what replaces it.
