We're always looking to mix 2D and 3D in our work - and that includes in our work process. A lot of the time, we're switching from 2D to 3D and vice versa. In this case, we rendered out the 3D elements first, and then we took that in and played with the color palette by simply scribbling on top. We like that our work process is flexible and we're able to do what works according to each project.
