Beautiful work, everyone!
I remembered a
beautiful post by Whitaker here, appropriate for anyone researching the brushwork you're seeing in the workshop. I've linked to that thread, but the image seems to have vanished.
Beth, if you're going to continue with photo resources, I suggest starting a new canvas. Use your workshop piece as a "color study". You don't want to bury the fresh, vital lessons learned in that memorable week. Keep it as a reference point in your growth.
