Chasm's Call - Community Render Challenge

My submission for the Chasm's Call community render challenge‬. I only had one week to work on it before starting a new job, which is why I decided to use existing assets like the helicopter, the cars, and the character. This kinda removed the fun of the challenge for me because I mostly participate in these challenges to refresh my Blender skills and learn something new. Just downloading random assets from the internet goes against this, and in the end, the render doesn't really feel like your own anymore (at that point you might as well use AI...). I started with the city environment and didn't have a good idea for the foreground so I went with the simplest animation and just made the character jump off...
