I painted two little sketches of the same flower recently. I wanted to experiment painting one tight and one loose. Both are painted from life. They're also cell phone photos with glare, but you get the idea.
At first I was very disheartened with the looser one. Now I'm not as sure.
I was taught to paint tighter but have been spending years trying to "let go" and paint it more abstractly/loosely. It's not easy.
