Charcoal sketch

I've been frequenting a forum lately that is for artists who do pet portraits. Every once in a while a photo is posted as an art challenge, and if you wish, you can post your drawing or painting based on the photo. Recently they posted a really cute photo of a foal. I loved the picture so I decided to try it out. I have some willow charcoal sticks that my sister recently gave me, and some new Nupastels in various shades of grey. My sketch is done on Strathmore smooth bristol, so the drawing is very smooth. Like I said, it's a relatively quick sketch (about 2hrs of work, compared to about 10hrs if I had done it really well in pencil), and I didn't worry too much about the proportions.

It's for sale if anyone wants to buy it!
