Re: Need Help with Traditional Approaches to proportions and Likenesses
An excellent way to train your eye for accuracy is the Charles Bargue drawing course. Itís a bit of a chore but it will teach you how to measure, if anything. Look into the sight-size method, too. Loomis etc. is great for constructing humans from imagination and breaking down the figure/head into basic forms, but is not exactly about getting the likeness down in portraits. There is also a course by Dorian Iten that focuses on accuracy that has some useful exercises, it can be found on gumroad. Next to these resources, one of the most important things to train your eye is simply mileage, so keep observing and drawing, and then some more!
