I managed to make some quick portraits during the Symposium, trying different materials. The first is James Richards, during the Talens workshop. He is instructor of one of the workshops.
I experimented with (Talens) ecoline, I had never tried that before. It's water soluble.
This is Kiah Kiean, a fantastic sketcher. My Bingelrade drawing was inspired by his working method. I used graphite and water soluble pencils in this drawing.
And this is Evelyn Huang, she also participated in the Rembrandt workshop of Fred Lynch. I had to make a quick inkline drawing, with as little lines as possible.
Chinese ink applied with bamboo stick, and waterproof sepia acrylic ink.
