I read that you have to paint 120 paintings before you get any good. I've given myself a challenge to paint a painting a day for 30 days.
Over the past few days I've been practicing with not much success. After reading a lot on the matter, I pared down my efforts for simpler subject matter and have taken the time to sketch them first with simple drawings showing the light values. The tulips turned out OK, but this is after I scraped the paint off the flowers twice. Daily routine. Sketch. Shade. Paint.
