I won't lie, this needs to grow on me first, but it's a great tune.
Edit: So yeah, it grew on me - the only complaint I can really have isn't even related to the song that much (I think the animation could use a more fast tempo bits). It's very "Cheshyre", so it might seem a little average compared to your other works, but it's just subtle - there's plenty of depth and uniqueness to it.
