Warm up sketches help me to experiment or try new things first thing each morning. They’re not highly detailed or finished art – I usually spend anywhere between 5 minutes and half an hour just focusing on the thing/technique I want to learn more about. When I’m busy, it’s important to me to find time to do this because I lose track of myself, especially when working to prescriptive briefs or doing a lot of copy-artist type work.
Today I was thinking about backlight and I tried a different eye shape – around 15 minutes.
