Enter doubt. Being critical of ones work is different from doubt. Striving to see your own work objectively and making adjustments is a positive thing. Doubt lives at a deeper and potentially more destructive level. It may simply be Winter setting in - less daylight making it harder to see bright spots in my work. But the feelings are real. Doubt starts you questioning the whole enterprise. Your abilities, your motivations, even your basic premise all become suspect.

Note: I don't feel nearly as bad as the model appears to feel in this drawing.
I think some self doubt is helpful. I have known artists who just plunge ahead with little or no reflection or doubt. I can't say it's good for their work. The challenge is to not let it bog you down or take over.
