at 0:35, the arp that comes in sounds a bit too much like an unedited preset. It gets better as you speed it up and increase the resonance (or cutoff?), though.
1:40 is good, sounds full. The kick is nice and prominent. Like the pause at 1:53.
2:19 - again, not a huge fan of that arp the way it sounds in this section.
The cutoff automation of the main lead at 1:32 and 2:34 sounds distorted in a bad way, but I'm not sure what you can do to fix that. Use a different filter?
I like the concept of the outro, but the piano could sound more interesting. Sounds a little bit empty, so maybe add some delay? That might create problems when automating tempo, however.
