I created this tutorial through Gnomon Workshop, covering the process of how I would go about creating a 3D illustration of a stylized character from start to end. It begins with the concepting/composition process in Photoshop, sculpting in Zbrush, a bit of Marvelous Designer, further modeling in Maya, texturing in Substance Painter, and final rendering in Maya/Arnold.
