This is so stupidly personal, but I kind of wish the echo on those synth boomwhackers was a little less pronounced, but on to some serious analysis, I like the sound of it a lot. Especially those chords with the ever so light vibrato on 'em, those are beautiful. The song doesn't venture very song, but you know what? I think you captured the 'space abyss' tone pretty spot on, so you're gettin all my stars.
...please please tell me what particular vst you're using for those chords, if you want, no big deal
