I put together a big, fat sketchbook PDF, featuring 190+ pages of doodles, notes, sketches, drawings and miscellany, from 2009-ish to 2012-ish. You can buy it for a single god-fearin' dollar at gumroad, and I’m posting some of the contents under this 'doodle-book' tag on my tumblr.
This picture, as the cleverest of you may have realised, is the cover I made for it.
Haven't done much 'finished' art lately, but I've been putting bits and pieces up on my tumblr, so check that out if you haven't yet. EDIT: For paypal lovers (?), the Doodle Book is now available at sellfy too.
