Most of the time if you step back for a while or come back to the painting the next day, you will see things you want to add or delete from your paintings. Or if you are working with an instructor, they usually see it immediately. I went back to this painting today and made some changes. I noticed when I went back to look at it that we were on a street sloping downhill. I had painted as if they were all on the same level. I went back and made my corrections. I also started a couple of other small paintings. A few are figurative and one is of a dog photo I took awhile back.
