I'm doing Proko's Portrait course, trying to go in open minded with no assumptions but it's proving tricky. So far I have just covered the videos on the Loomis method. Are the drawing exercises meant to be done of random heads (minus features) from your imagination, say, just a featureless head pointing in random directions? That might be where I am going wrong. I think I find the size/shape of the chin tricky as well. I know my drawings aren't great, they'll need repetition. I would just appreciate being told anything glaringly obvious, with respect to the course that I am following. Lastly, is it ok if I keep updating this thread as I progress through the course?
