This last batch of pen drawing is great. Good studies all around. By the way, I just wanted to drop in and say, whenever I see the title of your SB, it always inspires me to just sit down and work a little harder. So thanks for that. ^_^
Great Bridgman studies! The faceless guy from post #172 is looking good in terms of lighting and values so far--it'd be cool to see it rendered a bit farther. You could use those reddish tones in your background to add some really good color variation Keep going!
I couldn't tell those studies were drawn over pencil - the pens lines have a lot of strength all on their own. And the studies themselves look great, you've managed to capture some of the power of Bridgman's drawings.
