I constantly struggle with what to paint. Sometimes I have endless ideas, other times, no ideas. I do often paint the same thing several times in different sizes. A lot of paintings intended to be framed end up being studies, but I have always believed that you learn something from every painting and never consider even a failure to be a waste of time.
Feel free to use any of these photos. I still see things I would do differently in this one so I might do another one.
This shows the major stages of a painting, starting with big shapes, then refining as you go along.
