Lizzy 8x8 inches watercolor pastel

I have a bad habit: adding pastel to watercolor. I'd like to have pure watercolor, but I just can't seem to leave it alone. How obvious is that?
This is about my 4th attempt at a portrait and I'd love to learn how to get that luminous skin effect. Thanks for your tutorial. It's one of few on Skill Share about portraits. Constructive criticism always appreciated.
