About 3 or 4 weeks ago I was invited by Polly Jackson to join in a paint-off. We were all to paint the same subject, in this case, a realtor called Trudie. Here are the results.
Please visit Polly to see them in more detail. Mine's bottom centre. Next month the subject is a cow named Daisy.
Polly also has released a great instructional video via mindbites.com. Here's a link to a 60 second clip of Polly showing us underpainting techniques when painting with acrylics. It's really worth the $3.99 price tag.
