the fade in is really nice
nice and full, like you said it's not mixed the greatest, but at least you are aware of that. And yeah it's just chords but at least they have a cool presence.
That swoosh effect is cool - and then yeah things get a bit muddy but I like what you were going for - if it were properly balanced this part would have a much greater impact. It feels like I am almost standing by a cosmic orchestra!
I liked the whoosh, but I felt the outro kind of didn't fit with the ending - oh well - not bad!
