Hi there. You can add more shading to give some more depth and maybe some warm light?

Hi @Jo Edgehill, this is a good study. It is not that easy to draw a tilted head. I like the expression of the girl, the colors and how you did the hair. The shadows you did are not consistent. Because of the shadow of the nose I would say the light source is on her right. But then the shadow under her right jaw i strange. And take a second look at her eyes. First she seems to be a little bit squint-eyed. But I am sure you can easily fix that. And you shoul paint her irises like circles, putting the pupil centered into the iris. I did a quick overpaint to clarify my thoughts.
