The first idea was a portrait with some draw over and one of the requirements was a metal jaw. Pablo broken his jaw few yrs ago and today he literally destroy skateboard as he chew skateboard as it was chips. 

But the guys from 4M Skateboarding ask me to create something more cartoon, something more "Simpsons"... so I did a Cavalarizilla... eating some decks and walking over the city...

Sao Paulo Skyline

and finalize the art with buildings in the skyline.
