How wonderful that painting in the Impressionist style is giving you so much joy! I’m not exactly a painting expert (just look at me–I’m very bland looking, aren’t I?) but I’m sure there are technical skills involved in Impressionism; just maybe different technical skills than you have used before … or technical skills you know but used in a different way. I understand one way to develop skills is to do small studies of the same image. Since they are small you can practice and compare different techniques and skills in a fairly short period of time and further develop that way. The important thing is to keep painting and learning and enjoying.
