I've been applying for Illustration/Concept Art jobs and an Internet Gaming Compsny had a bit of interest in me. After the interview, they set me up with a mock project to test my abilities to their requirments. The project was pretty simple: They had an exsisting puzzle car game that they felt looked a bit out dated. The system and mechanics worked fine, it just needed a face lift. So they asked me to redesign the game with a New York City theme to it.
So here's some of the stuff I did for them....

Here's a little example video of what it would all look like in-game. Apologies for the crap compression!
