I am working on a two week pastel painting, a demo for my Tuesday night class. I will finish it up next week, but here are some in-progress images…
Note that I am keeping as loose as possible, with overlapping edges that I can refine as needed. Symmetrical objects like vase usually need tweaking near the end to make them ‘feel right’.
BTW the apples are real, but the jar of peonies is pure fiction, just donated to my pile of props by a business neighbor.
