I recently attended the Woodstock School Online Live Classes. These paintings are my copies of demonstrations of glass by Karen O'Neil. Glass is abstract and challenging because there isn't much to see. It helps to have something that adds contrast to the glass or a couple of highlights that make it shine. It's not about painting the glass, but what's around and behind it that makes it interesting.
John Bokor is a painter who I just discovered and whose works makes me happy. He is an inspiration to me to paint more complex still lifes.
