Here is a new self-promo portrait I just finished of New Zealand's fourth most popular guitar-based digi-bongo acapella-rap-funk-comedy folk duo, along with a bit of the process from sketch to digital paints. Owenfreeman.com has also just been updated with a bundle of new sketches and illustrations.
Also in case you haven't seen it there is a fantastic Drawger post by Yoku Shimizu detailing the process of a new portrait she did for Golf Digest. Can't recommend it enough.
