I think the tutorials are showing. This song is ripe with experimentation, but it's almost to a fault. Don't get me wrong, all of the fills, filters, and gates sound really cool...I just think they might be a bit overused and take something away from the track as a whole...
Where is the kick drum? I suppose it's ambient, but I still wanted more of a beat. The synth is bassy enough to call for one. I'm a sucker for beats, call it a bias.
The vibe on this is great though. I get that "You should feel nice and happy but you don't because something is just... off" from this. The piano and lead synth create an interesting contrast, whereby both want to be uplifting but the other counteracts it and brings it down. It's some combination of the melody and tone that does this. This is mastered very well, I might add.
Keep it up!
