Sounds nice, Antti! It's got your signature "feel", perhaps a bit more mellow than others but still there.
I'd try creating a bus just for reverb and use Sends from each track to vary how much reverb each track gets. That's a fairly simple way to get everything in the same space but not on top of each other. And if you wanted to go a few steps further you could use a few different reverbs on multiple busses, add an EQ after the reverb on each bus to "mold" them as a cohesive unit, and then vary the sends from each track to one or more of those EQ'd reverbs. The possibilities are almost endless...
