The cartoonist behind the award-winning webcomic Lackadaisy, Tracy J. Butler, has produced a brief guide to drawing expressions. The guide, which includes tips about unlearning bad habits, reference, loose sketching and, of course, practice is one of a number of guides showing how Butler produces, draws, colours and finishes her comic.

Lackadaisy, the story of anthropomorphic cats in the speakeasies of Prohibition-era St Louis has been appearing online since 2006, was recently published in book form and can be read for free from the start here.
