How do I create a cutout platform character with animations made in Timeline Plugin??

I've made a attempt that still glitchy, if someone could help me would be a great help!

If you move the player you'll notice that some parts like Head, LeftArm and LeftLeg go out of the player hitbox. I don't know how to solve it. Tried a couple times but no success. The controls are Platform standards by the way.
