Angel 18" x 24" oil on canvasAngel posed for a portrait group I attend last year. I was never happy with the painting I did so I pulled it out recently and reworked it. I think it's easier to work on a portrait that is close to life size than to paint the smaller sizes I usually work on. And of course, photos are always more difficult to work with, but easier if they're photos I take myself. Then I can adjust the color in Photoshop to match what I recall. The real problem is with the room where we paint: there is a lot of reflected light from windows, which changes as you paint and a few overhead lights tend to turn on and off at will, which drastically changes the lighting as you're working.
This painting is still not perfect, but it's better than it was and I'm tired of working on it.
