Can you guess which of these took 15-20 minutes, and which one took almost a full day? Well, I wanted to do this to prove that a painting can be done quickly and effectively. In this I wanted to capture the essence of the scene; like the light vs. darks and the general layout, and perhaps notes of color. The larger one took most of a day. It really is not that much more detailed than the other. They both capture the scene. I could work on the smaller one more, but this is all I needed it to tell me right now. I think this is a very valuable skill to learn well. I will be doing much more of this quickk study to see what I can do with it. I would not consider the larger one a complete painting, but I was at a point of overworking it and decided I had messed with it enough. I will try it again another day.
