It's cool that this is possible, but it's missing some very important subtleties which make professional animation look "right" or even "real". As it is, there's no sense of compression or snap at the right parts of the movement. 2D character animation has a lot of exaggerated distortions of objects to make them look like they land on the ground or bounce. The sense of weight and inertia is critical.

These aren't necessarily great, but this page[0] does touch on some of the basic concepts. "Squash and stretch" is a key thing missing. Also while in the demo you're dancing not walking, a walk cycle is a very basic thing which is often done poorly by even supposedly professional companies. [1] It's really important for the "contact" part to seem like it's happening. Getting feet to plant themselves on the ground and look like they're not swimming or sliding around is a challenge.

[my father worked in animation for much of his career and would complain bitterly about badly done animation, so I guess I can't unsee things with his critical eye]
