In this three-part series, Chris Legaspi covers everything you need to know about beginning portrait drawing, from start to finish. In this final lesson of the series, Chris goes over the last step in the portrait drawing process: rendering. Chris will do several demonstrations throughout the lesson, using a variety of different materials and stylistic approaches. Following the shorter demonstrations, you will have an assignment that will give you a chance to put these concepts into practice, and then have the ability to watch Chris’s version of the same assignment. The lesson will conclude with a three-hour charcoal demonstration of a male, allowing you to take in every step of Chris’s rendering process from start to finish.
