I'd work more on the animation, or rather cleaning up the mo-cap
How jerky it is right now is really distracting to the story and can be confusing to read what is happening. You have to remember, just because you do an action in Mo cap doesn't mean it will be read as that action when its in the CG space, you/your actors need to stay super conscious of body movements, positions and silhouettes in relation to the camera.
Also just an aside, your credits are way too long. Thats also distracting because I stop thinking about how I liked your short, and start thinking about how long those credits are and all the time I'm wasting looking at them scroll by
