Here is a small Personal project, a low poly, stylized, city environment that I built completely using Maya, Substance Painter, Substance Designer, and Unity Game Engine during my free time.
Here are some screen shots, and a short video of me driving around the environment with a basic car controller.
and at 2:05 I show the scene from an areal view.
Because I made the buildings, props, and textures they are for sale and you can pick them up here: https://cubebrush.co/addison3d/products/61tusw/city-environment-kit
