He made a great start, capturing a very good likeness. This was a "drawing" phase in thin, diluted brown oil paint, getting the proportions and large shapes down, before moving on to the darks, mid-tones and then lights. He has quite a presence and is very personable and fun to listen to. He made sure to describe the steps he did and why; it was really useful listening to him talk.
He has some work in the show this year and a great web site. This includes some video clips of him painting on the BBC.
