Achrono: I guess they've done them with skin before turning them to skulls. That's it.
The game is full of sterotypes too. Like Maximino as Vito Corleone, or the french waiter like some kind of sissy, or the rest of characters taken from Casablanca.
It all helps.
I remember the bad guy from The Mask, VampireNomi. He shaped the mask related to his personality, taking more square edges than Jim Carrey's character.
It makes me think of some bad guys from the Marvel comics too.
Thanks b0abi Wan!
Me, inspiring? That's not bad. Look for Guadalupe Posada's work for inspiration if you have a broadband connection. That's better.
