Colored pencil. I added more layers of value (dark and light) as well as color and detail. I used sienna brown, black, true blue, white, and dark brown. Think values, values, values!
Acrylic. This is the first pass of acrylic on the hawk. I first painted the background blue. Then I mixed several values of brown and quickly laid in the hawk (very wet paint). I did the white and black areas as well. Then ext step will be to adjust the values and add details.
