Got a gig illustrating some Aztec and Inca myths for an educational publisher. Usually never take on this kind of work because the deadline is always tight, the art direction usually overbearing, and the money terrible.
But I was intrigued by the job because although I had to familiarize myself with the style of art, I would have a lot of freedom to interpret the text because there wasn't much visual material out there to research.
Had quite a lot of fun with them: always nice to have a new challenge. Here are a couple.
