Andre From My Sketch Book

My plan to finish the oil portrait of Andre went out the window today. I did however sit down and pencil sketch him again. I've wanted to practice sketching his mouth as I can see now, this is giving me trouble and capturing the correct expression on the painting has eluded me. Having him come and sit has been great and the pencil sketching has given me some insight as to how I may now finish the painting. I decided to put this up for auction as I went further with the sketch then just the mouth and I'm curious to see if a portrait as interesting as this will sell on line.
