Underpainting for the Center Panel

Here is the underpainting for the rainy section. The idea is a rain shower falling on a lone autumn leaf.

Unlike my previous work where the underpainting was done purely in brown and white, this needed color as the glazes will be very subtle. I plan to add some light texture to the surface to suggesting a rain shower, and add some thin color washes to increase the effect. To provide a focal point for the work, this will be the only area using texture.
