Portraits, Caricatures and Master studies

Another Caricature of a co-worker.  Still struggling to be pleased with all the line work.  Usually I like parts for 3 different versions, and never should they all be on the same page, literally.  Another figure drawing attempt, another Kollwitz study, this time in charcoal, and finally some shorter 10 mins drawings from photos on charcoal paper with carb-othello paster pencils.
