The walk here sticks out.
For one thing, it's not a cycle.
It very well could've been a cycle, but it's not.
Here are three similar positions, the passing point drawing of the walk.
Drawing 1 (numbered arbitrarily -the others follow)
While the character's expression changes somewhat and she would break cycle for the final few drawings of the scene there's only one reason I can see that she was given 40 or drawings in this shot instead of 16: her boobs.
The breasts wobble at a different rate from the walk. It's a kind of brilliant touch to the animation, it would have cost a few hundred dollars less to just cycle and pan her. Even though it's not the most expressive animation, the idea behind it is sound.
