Is this shading good? Or should i try a different one, if so what shader should i use?

Doodles i made at school

I'm trying to improve with drawing hairs (especially female ones)

Any Feedbacks?

All feedbacks are appreciated

So naive... So gullible...

I know i said i won't make drawings until i learn how to animate but i'm just burned out and want to do something i enjoy
