While the use of a ticking clock was an all-too-frequent appearance on most of the submissions (mine included...), I do quite like how it brings us into the opening!
Loved the entrance of the drums and electric guitar, and the slow buildup of intensity! The panned voices in the next track are really cool, and I love the 7/8.
For this final track, I want to caution you against this all-too-common error. It seems like you've taken the same 2 bars and looped them, then added on/taken away instruments throughout the rest of the track. While eventually the chords and things do change, this repetition can subdue the listener's attention.
All in all, you did an amazing job with this soundtrack, and I enjoyed how you varied each track. Good work, and keep writing!
