I love the spontaneity of certain paintings, but some times an error occurs and you have to go back and fix something. A lot of times my paintings come easily for me and I don't sweat them too much, but once in a while I have to put my proverbial blood, sweat and tears into a work.
I recently painted a painting of my dad sitting outside and I loved the overall light and feeling I was able to capture. The painting took a little over an hour and I photographed it and called it finished. A lot of the painting is impressionistic and even my dad's face looks unfinished, but the thing is that that was on purpose and not in error. But I later realized that I forgot to put in the upper portion of the chair behind my dad on the left side of the painting (as indicated in the image below with the red arrow). I want my paintings to be intentional and in control even if they appear less finished.
I'm a purest when it comes to painting alla prima and I believe in capturing the transient moment and then called it finished in order to leave the spontaneity and not overwork it. The problem was that I was losing sleep about that missing chair part. My style is fairly impressionistic so a lot of people probably wouldn't notice, but I noticed and it was bothering me. I knew it was an error.
So what I did was I set up the chair back outside under roughly the same lighting conditions and I fixed it. It only took a few minutes and now I finally feel the sense of relief that I get when I do something right. It's a hard thing to judge, but I knew I had to fix it in my gut and I always trust what my gut tells me.
