Yo wassup.
I like the pads that fade in only to cut to another pad. In fact I was experimenting with that idea a while back, it's a fun one.
I think the build at 0:55 is a very traditional ArcaneSoulBuild (tm). I feel like when the lead comes in the pad should too so that you really feel the transition.
Sounding good, well mastered, good sounds. Melodies though. But you know that already... You should try using different lead sounds. Maybe piano? (You have probably already done this and I just don't remember.)
