I recently enrolled in Schoolism for Nathan Fowkes Environment Design course, and just completed the first assignment, "Standing on the Shoulders of Giants": 10 hour long studies! I found an original painting that I love, and then attempted to get it's values, color, focus and composition in about an hour. My study is on the left or on top, and the original os on the right or on bottom.
I learned a ton and struggled a lot, in a good way. I was working that uncomfortable edge. So far, the class is fantastic. Nathan Fowkes give concise feedback that is different for each sample student, which makes even the subscription feel like a very real class. I'm treating it as such, and am watching the class on Wednesdays, and "turning in the assignment" the next Wednesday. So, will be posting my work for that class here every Wednesday.
