A Girl and Color Pastel

First time using color pastel. It's hard because
I'm going to draw a face of a girl. You must be careful in putting hard stroke it must be light. Don't put dark colors first like black,dark brown and other, Light colors first.

Unfinish girl face.
In this photo I never used dark color.

This time I used dark colors for the shade and shadow.

Thank you and hope you like it
