I did a couple of portraits for some good friends recently. I made a conscious effort to get back to the loose brushwork of earlier pieces, and to stop perfecting every minuscule detail. I was so relieved and pleased with how they came out that I had to dance around the house a little bit.
I had to remind myself constantly to work quickly and to stop dab-dab-dabbing in order to get it just right.
Instead: commit. Then let it be. Doing less is so much harder than doing more.
But I feel like I'm finally getting the hang of it, and these two did a lot to restore my confidence.
