Short answer: Looks cute, but also wonky. I would say look up a classic cartoon walk cycle and try to make that but with pixel art, and once you can copy that go stylize it.
Some notes from the long answer:
- Legs move from the hips and bend at the knees, or else they look really stiff
- Ankles don’t move feet forward and back like that
- Yes boob bounce good, but this is too much. Also the shape should change a little.
- Face is cute, good job
- Hair should either be 100% static or animated other places than just around shoulders. Maybe leave it static for now
