work in progress: apples and pot

I worked for about two hours on this the other night, but haven't had the chance to upload or go further with it. I am working from a photograph from the reference image library at www.wetcanvas.com . It will be an 11" x 14" watercolour painting. This value study is done in graphite, with charcoal for the darkest value, in my large sketchbook. I apologize for the poor lighting - the grey rectangle in the upper left is a shadow, not part of the drawing. I'll post more as I work on this.
