Just finished this. It's my first painting using a photo from a site called "Paint My Photo" which I've been interested in recently.  The photo is owned by Ainslie G and I wish to credit her here as well as on that site.  What first interested me in her photo was the strong shadows and dark/light contrasts.  I printed her photo in black and white before using it as a source.  As you can see I became more interested in the background textures than contrast and shading.  I do like the result though.
