I love most of this track but let me make some suggestions:
- I find the intro too long for the total track length (I mean, the track should be longer or the intro shorter)
- the breakdown at 2:35 works, but maybe you could introduce some additional instrument or sound when returning to the baseline
- some variation in the melody would help a lot (at least some key shift)
- this track deserves a great ending, or at least a more club-friendly outro
