I am beginning to paint some highlights and shadows on the feathers of the first cormorant. Again I am using Winsor & Newton gouache paint with liner brush. For the highlights, I use Yellow Cadmium Pale mixed with Permanent White to make a highlight colors for the feathers in sunlight. Some of the darker highlight colors will have Jet Black and less Permanent White. For the shadow, I took Pthalo Blue, Cyan Blue, Jet Black and Permanent White to make a variety of shades for the feathers in shadow.
For the brushes, I used several liner brushes that ranged in sizes from 0, 1 or 2.
