Hey man, thanks for stopping by my thread. Your sketchbook is looking good! I'm in the same need-to-study-values boat as you, and it's nice to see you also like doing portraits.
Looking at your first drawings and paintings I'd recomend you use less black in your paintings. Nothing is ever black (this was talked on the portfolio review week, lots of folks got the 'too much black' critique). The portrait on the #22 post is awesome! Keep doing that.
Also, how was the schoolism course?
Keep up with those studies, man!
