This animation is fantastic! I absolutely love it! It’s super creative and very interesting.
However. A few things.
Are these notes in the actual animation?
Also, the sword, why does it have that one irregular bit sticking off the halfway point on the blade?
There are other, more minor issues, but these stick out the most. I’m sure another, more competent spriter could explain better than me.
Still great overall, and better than any anim that came out prior to, say, 2014!
