Again, the big brush for as much as I could do. Also, I tried to get as much pigment into the skin as possible. I notice that when I am doing a timed painting with my painting group (bad light, glare, etc.) I can't see very well, and since the timer is going I just have to make approximate decisions and get on with it. The skin always looks better than when I am working on my own, and from photographs. WEll, now that I write that, it could be one of the differences between having the live model and having an already interpreted image in a photo. Whatever. I think the time pressure forces an economical reduction of detail. I wonder if you can learn to do that.
