Player Animations Mod for MCPE adds animations that includes walking, sprinting, sneaking, swimming, riding, and more into Minecraft. It will make your character animation look more realistic and the bending of the character will be more comfortable, I especially like the running animation here, which enables Steve to finally bend down and run forward, which is more realistic.
