This is really neat, this art event The Promised Land Art Festival has a few lectures free online.
I enjoyed the lecture by Peter Han on his sketching process that can be applied to Product Design or illustration for problem solving.
I like how he broke down what Drawing is which is intent awareness, simplicity and expressing it.
“See with intent and awareness. Visualize through simplicity. Express without effort.”
– echo from Norman Schureman
