I started this sketchbook on my trip to Boston back in November. I don't think I've ever finished (or at least FILLED) one so fast-- even though it was only 9 x 6 inches and 70 pulpy pages.
Some people make better models than others. After the shop emptied out (post lunch), I colored in a page of sketches. The "jaundiced" girl wasn't really yellow. I just got headed in the wrong direction trying to make her look pale in comparison to her brunette friend.
