Occasionally, when I have a model pose for my classes, my students and I pay her extra for some photography time at the end of the class. Here's a sketch I did during class one day recently from a photo of Denise. It's a new pastel up for auction on Daily Paintworks.
"Denise with Striped Fabric" is a 12 x16 pastel on Pastelbord. You can go here to view auction. While you're viewing it, take a look at my other pieces still available.
