painting a model

Today, I painted a portrait in oil. It was fun with a group of other artists doing 20 minute poses of a model (for a total of 2 hours.) I didn't get a model release to post it on the internet, so I will not include a photo of my painting. I was pleased with it, as I rarely have done portraits. This experience made me want to try again. I have rarely had the opportunity to paint someone sitting still that long, except sketches at airports. I had a friend who lived in a third world country who said when she lived there, she painted people all the time, but didn't get the chance to paint them here, because they moved too fast.
