"CRAAAA!" (said the Aztec Birdman)

...born as a silly thought in my mind, the aztec birdman soon became a little obsession:

the inspiration came out from a mix of pre-Columbian cultures + the character "Horus" in Neil Gaiman's "American Gods" + something 'bout Carnival in Venice

Done basically with blue pencil, ink, markers and a little editing in photoshop for the backgrounds.
