One thing I have been doing differently that I think is working out well is to paint the watercolor directly, with no sketching or pencil. Large shapes are blocked in with very light watercolor, then shading is built up with successive layers of more color and more detail. All three of these sketches were done that way. I think the hardest part for me is to stay focused and don't get impatient. I find I run out of energy to continue after about an hour; then I get lazy and stop really looking at what I am painting. I need to stop at that point, instead of continuing to mess with the picture.
This is from the new outdoor art exhibit from the San DIego Museum of Art in the Plaza de Panama area of Balboa Park. I wrote Art in the Park but that isn't the right name, it's Art of the Open Air, part of the #freetheart campaign. There are a number of wonderful pieces, including a Rodin and Miró. I like this one by Lynn Chadwick, The Watchers.
Go make art!
