Very nice! Love the accordion as an instrument in here as well as the clock, especially at the speed up after the intro. And I am utterly in love with the pitching of the bell/gong sounds at the end.
My nitpicks: If possible, I would move the two accordion lines further apart or remove one octave of the doubled notes from each, as soon as both are playing. Right now, there is significant overlap in the spectrum and especially starting at bar 89, when the orchestra track is also kicking in, those two arpeggio lines try to talk over each other, making the arrangement mushy and the individual voices difficult to differentiate. And while I get the cuckoo as a clock element, its presence feels somewhat exaggerated. If it were a more background element and maybe also introduced earlier, I think it might work better in this piece - as it is, it feels like a comic relief in a track that does not need one.
