Lot of lo-mid noise on your reverbs. Try turning down the FX wet and hi-passing it. These frequencies tend to gradually build up and muddy your mix. I hear it especially on the big boomy FX. You'd be surprised how little reverb you really need to accomplish the sounds you're going for.
Boom FX is too loud in the mix. I think I hear clipping at points.
Other than that, chill piece. I'm vibing with it. Synth bass could probably use some humanization.
2:56 is clipping pretty bad. I don't think a limiter would be a big enough bandaid for it. Protip, make sure your track peaks no higher than about -6 dB. If your mix sounds good here, it's ready for FX and compression in the master channel. It's hard to squeeze a track under -6 dB when you're used to mixing everything all the way up, but it's worth it.
