Very good film, great idea.
Few of my points, the footsteps on the steps at the girls front door sounded very boxy probably just a little bit of reverb could help it. Also maybe add a few footsteps when the girl is leaving emphasising the snow at 6.15 onwards.
I really felt I needed the sound of the girl breathing around 1.14, it would really enhance the scene.
ADR for me could have had a bit of reverb when the girl is talking to the driver outside of the bus but liked the environment for inside. A lot of the lines were out of sync which put me off but the quality of recording is very good.
When the first bus pulls away from the stop it changes gear 3 times before it has moved away from the shot (is that normal?) and it fades away too soon.
The music to the track is spot on its great. Hope this helps, nice work.
