I'm no animator, but it all comes down to how you use the fundamental tools at your disposal. How you use them to create variety and contrast in your animations, in a way that helps you express what you want. Can you communicate the shifting emotions within one character within a single animation? Here you have an animation where the expression of emotion is steady. She starts out expressing her anger and continues to express her anger. You can be more expressive by showing the change and buildup of expression. For example, by building and bottling up her anger until she then releases it.
The same kind of thing applies to anticipation of motion. Don't just animate a swordsman swinging his sword. Animate the effort put into swinging the sword, and then the sword passing through the enemy, and then the sword swinging free.
So, what can you do so that your animation has more "stages" to it? What if she stops talking on the phone after a little bit, winds up to throw the phone, and then throws the phone to the ground? How somebody accents the shifts between the stages, the timing, the weight, the poses chosen, the facial expressions, and impact of those motions is how you tell the difference between one animator's style and another. If I gave this prompt to several animators they would all interpret it differently and handle it differently. Because this, from what I understand, is where the world of animation completely opens and the number of possibilities explode.
