JUS is a style that focuses on dynamic poses and animations. Not something one whose just starting out should attempt. It's also very restrictive in size, and people tend to clutter things when attempting the style.
Your faces seem somewhat cluttered, your animations aren't dynamic...in fact they're stale. Your shading is off and well let's be honest here, if I were to see these next to JUS styled sprites I wouldn't think these was supposed to be the same style or even an attempt. EDIT: These are also very blocky. JUS is a fluid style, your lines are working against you.
My recommendation, start with a different easier style. Actually don't even follow a style just start pixelling. You'll build skills and understanding that will then allow you to mimic popular styles.
