I entered a contest and at least got an honorable mention, but they didn't show the images that I provided. You can check some of them out on my previous blog.

"Burnout Resurrection
Criterion's Burnout franchise has revolutionized the Arcade Racing Game Genre. Burnout's innovative crash and damaged systems have inspired others to create racing games similar to Burnout, but they have fallen short in overall impact. Till this day, Burnout's only real downfall is that their most recent game, Burnout Paradise, shocked and surprised many. It was so different that it attracted even more players with its new and massive free range racing world, and also scared away the arcade-only type racers that liked the old way of Burnout; racing in closed boundaries and traveling across the globe. Majoring in Game Art and Design, and being die hard player of Burnout, I feel very confident that I have a good grasp on what it takes to deliver.
