It's officially here! The little/RED sketchbook is available over on Gumroad! https://gum.co/uQAgZ
This 51 page PDF sketch collection features all the hero and villain sketches I've been posting over the last year or so. We scanned it so you'd get as close to holding the actual sketchbook as possible.
Go over to my Gumroad site, name your price and enjoy!! (Or, you can just get it here via the widget at the top right ;-)
Oh, and help spread the word to your friends! Thanks!
