I really like the vibe!
The first part is simple enough to leave space to what's potentially happening on screen, but present enough to set the mood, that's a really nice balance.
The switch to the second part surprised me, but got me shaking my head pretty much instantly :P
The repetitiveness of the first part was not a problem for me, but in the second part, it was a bit too much (in my opinion, of course).
But I liked it a lot, well done.
Thank you for sharing your work :D
