Hey like other people said the kick sidechain holds off for way too long, and the snare sidechain is either too short or not quite enough, youll find the sweet spot its pretty hard to. Your mixing and mastering was pretty good and your drums sound clean as can be, but the rest of the mix seems too quiet for the drums, probably because of the sidechain, but I wont pick at you for that. the chords in the first drop could've had a few more layers but yeah other than that, hope this review helps towards your future tracks, looking forward to them :)
