Drawing a head after live model. First We outline the main principles of portrait drawings such as measurement, discuss ratios, shadows and then work on drawing techniques. 3x 3 hours workshop. Last Year I participated in the BP Award winner David Kassan painting and drawing from life workshop in RHA. I would like to share those experiences that I have gained there. I wish to share all those materials that he uses, the technique and ideas that I have learned throughout his workshop.
