Avatar Emotions Bar Sketches

I did some sketches on how the introvert's emotions will look based on the energy level. Social bar can still remain a bar, but as what my tutor suggested, bars are very old school. Therefore, I tried using his suggestion to convert the energy bar to the introvert's emotions to show whether his/her energy is high or low.

This is the sketch of the introvert's emotions:
