The drum is well designed in general. For instance, the different percussions at around 1:20 and the small 3/8 pause before the 7 beats really prepares you to what comes next.
The progressive crescendo that starts at around 1:16.5 becomes to high-pitched at 1:20. I was expecting it to either 1) restart low-pitched and loop twice or 2) come with a modifier that somehow hides a bit the saw shape of the sound (i.e. be it distortion or literally a change of shape (not sure what to use here, but I see the raw saw shape of this instrument as a problem)).
This "raw instrument" problem affects in fact the "main" instrument of the first "drop" at 1:22. It gives me the impression that you worked less on this part of the song and gives it a less meaningful/authentic taste.
However, everywhere where there is bass, I hear this problem less.
If I'm not wrong, you used a low-pass filter at the beginning on the piano-like instrument. That was a good idea, and indeed makes a contrast with the introduction that comes next.
I don't hear those fast "integral" crescendo (with the piano) a lot. I think this alone makes your song quite unique and adds some depth to it.
To be honest, I feel inspired.
