Have you ever seen a piece of artwork done in Cel shading art style by Rare Reversee? Here it is. Cel shading art animation video by Rare Reversee. A pretty fun project both to work on and to learn from. FYI: Cel shading or toon shading is an art style of non-photorealistic rendering designed to make 3D computer graphics or artworks look three dimensional by creating flat colors on top of a base color, making the object look three-dimensional while still keeping that 2D effect in it.
