I recently did an acrylic demo of a tiger at otis for Daniel Lim's sophomore class. They were lovely and asked questions and laughed at my dumb nipple comments and stuff. Not my best work but I was pretty nervous. (Clearly it is still in progress.) I did the "bird-hat" painting the evening before to warm up in preparation. Both are a mix of ink wash, acrylic wash, and acrylic dry brush.
Aaaand an old sketch I just got around to scanning: I'm sending this and the acrylic painting it became to a lovely woman in NYC.
