Listened to the Stephen Silver "Artcasts" http://www.silvertoons.com/podcast.html whilst weeding the allotment today. I've never been any good at caricature work, but there was a readers letter that hit the nail on the head... unless you make yourself try these things, you will never get better. I'm looking for an adult evening class to get my sketching up to speed.
Finding it hard to make myself draw something today, so did a bit of colouring in PS. I'm guessing there are many easier ways to do this.
