Tower Defence concept sheet

This image was part of an art test. The brief consisted of designing 2 building tiles, some props and 2 characters (a survivor and a flamethrower unit respectively) in a post apocalyptic style. I wanted to contrast between the faction's warm colors and nature's bright colors, making the latter feel almost toxic and dangerous.
Even though the concept of the game changed eventually, this image got me the job. And the client was kind enough to let me post it here.
