First, let me say that no matter how much you love a painting you're working on or parts of it, if it's wrong, you must correct it. It's an absolute rule. There are no exceptions. I once did a really lovely painting of a huntsmen walking his hounds. His face was particularly well painted. After examining it more closely I realized that his head was just a little too big for his body. I put off repainting it for days but finally decided it just had to be done. I thought if I could paint it that well once, I could paint it that well again. That attitude gave me the confidence to repaint it without loosing any of the detail or sensitivity of my first attempt. If I had clung to the idea that I'd ruin it if I repainted it, it probably wouldn't have turned out as well as it did.
Anyway, I certainly didn't love this pastel. I knew it needed help. It seemed unsalvageable.
If you get stuck while working on a painting and don't know how to fix it, don't do anything at all. I like to sit and just look at the painting. It could take hours, it could take days before I see something I feel needs to be changed. Then I can't wait to start painting again. It never fails. I used to be rather timid about painting over something the second day. I work very quickly and would often get the essence of the thing down in a matter of a few hours. When I'd return to the easel the next day, I'd be afraid to touch it for fear of ruining what I had already put on the canvas. I learned to be patient and let the painting speak to me. Try it if you have this same problem. You'll be happily surprised.
