I have depicted a setting that is gradually turning toward sustainability. The main focus is wind power, and this piece is available for customization and licensing. The methods used to make this animation is a blend of warm traditional techniques, and wholly digital components.
I drew most of the background elements with pencil on paper. I then scanned and colored each piece before dropping it into a 2.5D After Effects scene. Clouds, buildings, hills, everything is on a separate layer and at a different depth. Sometimes I use the After Effects camera’s own depth of field to provide rack focus. Other times I manipulate this in individual layers, one at a time. This still looks natural enough, but helps a little more with moving through the shot.
The characters were animated in layers. The biker, for instance, was composited back together around a 3D model she was pedaling through the scene. The 3D elements were modeled, animated and rendered in Blender. Real world audio was captured outdoors and in the studio, then manipulated in a number of applications.
