Re: [chill] envelope 3 -outsides
I dig it, the soft pads early on in the background give it a really full landscape. When the drums come in fully, the song really evolves deeper. Sounds very clean all the way through. Maybe the arpeggiated bass line can come through a little heavier, but honestly it's hard to give advice on a track like this without being an engineering expert. Sounds like your composition is on point, and the song is working.
The only thing I hear to work on is bringing up some voices and placing them among the mix. Around 4 minutes in I'm getting some interesting stereo ear-experience. Almost as if it started off a little too-panned (on the left) but it seems to balance out.
Just small things though really, sounds like you have an amazing grasp on what you're trying to create. Great job.
