Sean Cheetham, a very well established painter did a 2 day painting workshop on June 20th and 21st. This workshop focused on how Sean approach his personal gallery works from start to finish.
Sean explained what he likes to paint on and how he prepares the surface. Then he went on how he transfers his sketch on the board. He then demonstrates how he applies acrylic wash on the sketch first and then uses oil to paint on top of it.
Here are some pictures of his demo on live model on the second day of the workshop.
