I don’t normally do portraits because I think they’re really HARD. I find it much easier to draw the human body, rather than the face, but now and again I have a go. It’s easier when you’ve been drawing the model for a while because you get used to them. The face is not only extremely complex; there’s no room for even the slightest mistake because it means the difference between a likeness and looking like someone else. I’d had some practice with this particular model; I’d drawn her many times before so I had already developed a sort of ‘shorthand’ for her features. The drawings are pastel and chalk onto sugar paper and the poses were between 5 and 10 minutes. I’m pleased with the results; the speed drawing freed me up from worrying too much about being accurate and they ended up being quite good likenesses.

You are right, I find it difficult to draw human face and sometimes figures too…. but i of course overuse erasers when i need good eyes or sharp nose features, its all worth it!
