Interesting idea for an animation, in the form is a side-scroller. At first I thought the footage was actually fetched from a game (reading the description), but it is all custom right? The contrast between foreground silhouette and background color is nice, the music powerful, the change of weather probably the most impactful part of the animation, only thing that distracted me a little was how the cars didn't follow the contours of the landscape. Overall though, nice work!
