Broken Clock: I really like the progression from intimate chamber-like classical music to big epic swells. The modulation just prior to that point also feels really satisfying. The high strings and piano arpeggios give a lot of energy to the piece.
Part 14: This is a really beautiful piece and reminds me of the music of Joe Hisaishi. I think the transition into the pulsing strings section is really well done. My favorite part is the suspended fourth in the strings at 0:45. Overall these are very beautifully crafted pieces and I would love to see more of your OST ideas be fleshed out further! Great work and thank you for sharing!
