Lost a pupil after okay samurais tutorial

Hi, can someone help me 🙂 I am trying to learn skills in making my first character. I started by following Okay Samurays Wilk Character, and made him to raise eyebrows being angry/ worried and did his lids in same style. After I finished it, for some reason, one of my pupils is not showing. Can somebody give me any suggestion to help?

Thanks, Ana
