I haven’t done one of these in a loooong time. My reference was my reflection against a window with a screen behind it at night– the main light source was my monitor, and as I worked the colors shifted, changing the color of light on my face… This went into a loop until things refined themselves out. I really enjoy working with ambiguous live reference! I’d like to try a low-light life drawing workshop where the artists can barely see the models or their paper. Hmmmm!
