Section 1: The dominant pedal in the middle register being held that long is a bit strange, but works well enough.
Section 2: I think you channel Zimmer a bit too much here. Maybe I'm biased since I'm generally against his scores, but the octave jumps at the beginning don't constitute a melody to the audience. The scalar figure from the beginning does return, which is nice, but it feels a bit forced in, like a callback rather than a development.
Section 3: Well done here.
Section 4: It's a bit too similar in tone for the different tone of the story. The F# minor and reliance on low tones without help from the high end makes it feel less like panic, and more like confidence.
