When I need to understand how to achieve a certain technique, I generally find a good example and then try to reverse engineer it. This principle is as old as the hills, back when I went to school we called it a master study but I don’t know what they’re calling it now.
At any rate, I’ve always been a fan of the Neoclassical style in general and Gainsborough in particular so I wanted to do a master study of his technique, I hope you enjoy my results.
