I had some nice interest on my brief description of my pastel portrait process and thought I would post something on my watercolor process.
I like to get color down quick and don't like to go over the areas with many washes. I find the more washes and layers you use the less glow a painting has.
I start with large areas, saving the whites, and feeling my way around the form. I build up color and work the detail in bit by bit.
I add the background at different stages for each painting. Usually when I feel I have enough of the face value established to know how dark/intense... to make it.
I usually have a color scheme/temperature... in mind when I start, but don't fret if I change mid painting. Thumbnails/planning is good and something I do as a habit. But once in a while a painting reveals a new direction that I didn't think of. So I usually will go for it. After all, it is only paper...
