This is my demo painting I did two days ago for my One-Day Zoom Workshop. It was another successful one. The feedbacks from my 3 Zoom workshops so far have approved that using apps to paint is a remarkably effective way to paint. Beginner painters can quickly go through the hurtles of color perception and color mixing. My dream is to make the technique part of painting becomes so clear and easy. Artists will spend most of their time and effort on their designs to express their creativity.
