Really nice! Loved the transitions and most of the audio design. Only thing I could say is that I didn't like the continuity of the bird chirps. With a change in visuals I would have liked to hear a change in audio. I think it better impacts the shift of the environment in the mind of the viewers.
or just sort of fade them out like you are re-focusing your attention onto something else and you sort of forget about the birds, then bring them back when you get to the same scene again. that was tight tho. really enjoyed it
