It's a beautiful track, very calm and pleasant to my little ears. I have to admit for a moment I thought that multiple animators worked on this, both your drawing style and animation technique seem to change as the video goes: first you animate your character walking by sliding him around, then later you give another a fully handdrawn walkcycle. The line colour, strength and thickness also seem to change all the time, and the colours of just your main character seem a bit all over the place as well.
Correct me if this is wrong, but I have a suspicion that you didn't make these shots in chronological order, but we can still see you change and evolve as an animator. Because of that, it is strangely fascinating.
