I like this a lot
If I had to point out one thing to improve on, I'd say the bass is a little too heavy around the 1:50 mark.
And maybe drop at 2:30 could be softened a little on the high-end, it comes out a little harsh.
Otherwise I love the contrast in the progression, and find the calmer parts very soothing.
Genial!

The drop really took me for surprise, I liked it a lot. I would look again at your melody, it gets a little boring as the first few minutes go by. Consider adding in a few different instruments and melodic lines as the empty/spacious parts progress but otherwise cool track!
