This rocks!
I think the overall is really good, but here's what could go better:
1 - The whatever that sounds like an 8-bit bass slide at 0:13 is of sticking out too much. Maybe it would get better if you made it a normal bass.
2 - The ending is kind of silly, I don't like it. Doesn't really fit in.
Otherwise, you're great. My favorite musics were made by you. Peace!
