Adjusted some of his facial features (eye and nose) in pencil and started blocking out shadows with markers. Need to remember to pre-erase some of the pencil marks.
Also, I did some marker maintenance and re-filled most of them. Used the booster needle for the first time which was awesome, but overfilled several of them. It is super easy to overfill them with this method. Need to remember that like with all things, less is more.
