This isn't ambient...
however I won't downrate because of that, because this song is VERY cool!
The melodies and such are too busy for it to be ambient, but I love the melodies to bits, they're so cool! Your synth choices might not be in the best interest of the rest of the song, but I like the piano and bass and the drums are fine too. Anyway, I find this to be better than crystal keys and is my new favorite of yours. Good job man!
