Project: pick any book to create mock book covers. I chose the Tales of the Left Hand series by John Meagher, a fantasy story involving assassins, magic, and pirates. It is formatted as a "podiobook," which is an audiobook released as a podcast. John does a fantastic job narrating. You can find more info at the TotLH site, as well as links to both audio and ebook versions of the books. I highly recommend checking it out!
I drew all of the line art in Photoshop, printed it, then used gouache for coloring.
