You can see I am practicing the design of my brush work. This is the third painting in this series. Painterly painting style does not happen accidentally. It requires a thoughtful process. I am still in the early stage of my style design. I heard comments like this: so and so's painting is too stylish. It has a feeling of some degree of negativeness in it. It sounds like the painting is developed by following a formula. Personally, I am not against using formulas. When I was doing my scientific research work, I used mathematic formulas all the time. The same principle applies to art as well. However, the issue is how many formulas do you have? If you only have one or two, that is problematic. Moreover, if your formula was not derived by you, in other words, you don't know why but just simply follow the steps, then the painting will be boring. So my "two cents" is: 1). painting from life, 2). summarize your own formulas, and 3). cumulate formulas as many as you can.
