Diploma project: Character Design (for animation)

This is my diploma project for my university. The main idea was to create a concept of a character, which could be used in anime production. For this purpose, I chose my original character. Her name is Shizuka, she was born in a colony on Mars. Shizuka is a young mechanical engineer, who loves French fries, old music, and her job. Also, she loves her sister (and talks only to her).

The project was made 2 years ago, so it's time to show my child to the world, he-he. Frankly, t's interesting to see the difference between me in 2019 and me in 2021. I wish I could change some things and put more details and show her personality in the design.
But free to give any feedback! I'd love to hear your thoughts.
