Here are some sample sketches I prepared for critiques for my students at http://advancedcaricature.co.uk. On the beginner’s course, I have a lesson based around extreme exaggeration. This is probably my favourite lesson. I spend a lot of my time with portraits, and it can be very easy to forget what it feels like to exaggerate. We can easily get out of the habit, so the above is a good exercise. It’s an opportunity to let loose!
