The show was broadcast to 11 million PBS viewers each week, far surpassing his original one million student goal. His art style is a cartoon 3D style that is focused on basic drawing techniques such as foreshortening, shading, surface, size, overlapping, contour, and density. [3] His first book "Draw Squad" was released in 1988.

Cartoon rendering, also called cel shading or toon shading, is a non-photorealistic rendering technique used to give 3D computer graphics a flat, cartoon-like appearance. Its defining feature is the use of distinct shading colors rather than smooth gradients, producing a look reminiscent of comic books or animated films.
Shading is used traditionally in drawing for depicting a range of darkness by applying media more densely or with a darker shade for darker areas, and less densely or with a lighter shade for lighter areas. Light patterns, such as objects having light and shaded areas, help when creating the illusion of depth on paper.
3D shaders act on 3D models or other geometry but may also access the colors and textures used to draw the model or mesh. Vertex shaders are the oldest type of 3D shader, generally making modifications on a per-vertex basis. Newer geometry shaders can generate new vertices from within the shader.
This allows shading to occur only in mid-tones so that edge lines and highlights remain visually prominent. The Gooch shader is typically implemented in two passes: all objects in the scene are first drawn with the "cool to warm" shading, and in the second pass the object’s edges are rendered in black.
Popular surface shading algorithms in 3D computer graphics include: Flat shading: a technique that shades each polygon of an object based on the polygon's "normal" and the position and intensity of a light source; Gouraud shading: invented by H. Gouraud in 1971; a fast and resource-conscious vertex shading technique used to simulate smoothly ...
A sketch colored digitally with use of several different blend modes in order to preserve the pencil lines and paper texture below the color layers. Blend modes (alternatively blending modes [ 1 ] or mixing modes [ 2 ] ) in digital image editing and computer graphics are used to determine how two layers are blended with each other.
