I stumbled upon this workshop by accident while searching for art classes and thought the formula was great. This is my first time on a forum but I really wanted to give it a shot. This is my first study, Rocks at Nahant by William Stanley Haseltine.
Unfortunately, I don't believe I have captured my main observation which is the continuity. The line created by the rocks at the bottom left leading into the painting is stopped by the curve coming from the top of the rocks on the right, leading to the 2 figures. It is also aligned with the main wave coming from the direct opposite...I think this helps sell the impact of the wave. I spent most of my one hour trying to get the right proportions but I realize it would have been much easier (and more accurate) if I had started with the main continuity lines. I hope I posted this properly.
