Artists can be Their Own Worst Critics
Some artists can be their own worst critics. They may see flaws in their art, whereas viewers are enthralled by it. I think one reason why some artists are their own worst critics is because it's kind of difficult for them to be objective about it. They spend so much time on the art, looking at it, that they need to step away from it for awhile and come back later to see it with fresh eyes. I think if you do that you can at least be somewhat more objective about your art as an artist. You either need to step away and come back, or have someone else look at it. Christopher Hart talked about being your own critic in a post on Facebook. I think he basically said you need to think more positively when critiquing your own art. It's good to critique your own art so you can do what needs to be done, if anything, to improve it. But, you shouldn't be too hard on yourself.
