Yanju Stephens portrait

This was my entry in the challenge #OneWeekPortrait (2020) from Paintable (David Belliveau) and I've enjoyed it a lot!
I've learned a lot back then.
Critique and feedback are very welcome.

The model I used as reference for this portrait is Yanju Stephens (Adeyanju Adeleke, @yanjusofine_), she's very beautiful.
