The daily paintings I have been posting are a "one-session put the paint on and be done" approach. A more classical approach which is the way "Mandarin Orange-Classical" is being painted is to do it in layers with drying time in-between.
Obviously the classical approach takes more time and discipline but has a wonderful effect of depth that is very hard to capture in the one-session paintings. This is still a work in progress as only the first layer of color was applied yesterday and "whiffed" with a mop brush. This gives soft edges, removes any ridges of paint to have to deal with in subsequent layers. The next layer will be more specifices, edges, and highlights.
