The moment when you use kontakt but it sounds like fl keys haha im laughing so hard rn :D DnB and Ambience has something special to it - it's more relaxing to me than listenling to lo-fi cause i'm lowkey digging the drums in addition to the ambience xD
But yeah as la-yinn said, reverb can be useful but it also needs more space. Overlapping frequencies without like being concious about them can be something that just annoys :D especially your mainparts with the drums - sometimes it's too much and needs a cut in my opinion :D
But like in general the intro and the break is okay (maybe too much reverb aswell)
Coming back to the keys, well they don't exactly sound like fl keys - but different velocity wouldn't hurt either :D
Yeah that's alot of criticism BUT I like your track really much! It's something I could chill to :D Overall it's really good - you only need to work on mastering/ make small changes etc.
Good job :D
