Cons:
The angle of the kick and the slap is impossible to perform in real life.

The kick speed is too slow to hurt someone.

After the guy reacted to the kick, his hand was only static on air. His foot too.

The slap is too weak to be powerful.

Instead of showing acceleration, this guy showed deceleration while he flew to the other side.

Tips:
Show more body reaction while he was kicking, video yourself kicking and study it.

The angle of the slap should’ve made him go either down or sidewards, or both, instead of backwards.

Practice, watch the animations of the experienced and study them. You’ll learn.
