Xantor, nerd, SWAMP, and crocodilian, thank you very much for your responses.I am going to try what you suggested.

SWAMP, I will try them, and may ask more questions.

Crocodilian, her eye is big.
I was trying to make a cute girl. I put some anime flavors on her, but tried to keep her reasonably realistic.Eyes are larger by about 20%, and mouth, and chin are smaller like Japanese anime, but not too much.
I wanted to keep her reasonably realistic rather than anime style.
This is an experiment. What is cute. It is subjective like art. Therefore, it is very nice to hear opinions.

Thank you very much.
Himico.
