First of all, let me say I really like the sound! It’s a cool track, but in my opinion, you made a few decisions that took it from 100% good down to 80%.
• I would remove the lead synth (first at 0:05) completely. It doesn’t need to be replaced with anything else. It sounds out of place. It jumps out (in a bad way in my opinion) every time it’s played.
• I don’t like the new sounds at 1:02 too much. I would replace them with something very mellow (a small pluck or something), or nothing at all.
• The ending drum fill is a bit unnecessary. It feels like we’re going into a new section, but instead the track ends.
• I think the beat is a bit to powerful to call it ambient. I like the beat, and the fat sound, but maybe call it something else and put it in another category.
That is all! Best of luck.
