Hmmm, cool!
The motion here actually reminds me of watching someone walk through a pool, as it has weight of buoyant but restrained motion, which for this character is very haunting and works well especially with the ripple of the shirt's hem.
I would suggest if you wanted to how more effort or weight being transitioned in the step maybe try to show more activation, or effort in the muscles in the back of the leg.
But honestly I really like this kind of phased out trot you created here, and the Will-o'-the-wisp revealing the hidden arcane aurora is very cools and clever.
Thank you for making this.
