I'm informed its not actually a Mayan calendar (its Mexica and technically a presentation of the fifth sun … thanks for the heads up ) but here's the background piece from [link] coz a number of people asked to see it without the beautiful woman standing in front of it. Go figure.Pen and ink on paper, painted in photoshop. You can still see some of the ink lines on this finished piece - got a bit lazy after working on it for two solid days
