Noah Campbell:

When your character stands up, for a few seconds, his leg jitters a bit. This can be removed by checking your timeline and seeing if there is any misplaced frames of movement on the leg. Your character's lip also don't move when they speak, only their jaw does.

William Barry Eggington:

Good idea. Self motivating.

Forrest Stull:

Good pose choices! The next step in improvement is to find ways to link those poses with secondary movement rather than snapping from pose to pose
