My project for course: Portrait Sketchbooking: Explore the Human Face

I found a good number of referece photos, but then in the end it was a bit overwhelming to choose which one to use so I decided to draw a selection of a few instead.
I already had somekind of experience drawing portraits, but this project (and course for that matter) helped me to streamline my process and become more aware of the troubles I have and should improve upon.
