This is done from a photo that I received in a Christmas card from friends. My plan is to spend a little time each Saturday doing a portrait from a photo. I hope this helps me to see progress and do my own work, not just copy Sargent.
By way of evaluation, I think the first week's worth of drawing has been good for me. The chap in this drawing looks around 2, as he is in real life. I did a "from photo" drawing of my son a few months back, he looked about 8 or 9 in the drawing (he is 4 in real life :-0).
Three posts is enough for one day! Tomorrow I'll post another.
