The piano at the beginning isn't bad, but it seems over-processed and not super "real" you know?
The mixing/mastering on the percussion is solid. I really liked the initial drop into the bass too, it was sudden and had a good vibe to it.
I liked what was initially going on at 1:08, but when the noise cut out it sounded a bit empty. I think maybe some pluck synths would work well there, or perhaps some vocal chops.
At 1:31 there's a lot going on. I like the sidechain work, but there's too much for me to focus on and everything becomes a bit jumbled.
Really like the percussion work throughout, it all sounded solid and sat great in the mix. The high lead was good too, and wasn't repetitive. The track runs together so quickly and doesn't give the listener much time to breathe and process what's going on however. I would like this track at like a festival or something, but sitting down to listen to it in my spare time would almost make me stressed out in a strange way.
Good job though, it sounds professional and thought out.
