For this painting, I decided to start off with a white background. I then blocked in the owl, painted in the background using more transparent washes (hence the reason for starting off with a white background) and then added in the final details. Worked rather well and I am really pleased with the final painting.
Owl measures 6 x 6 inches and is painted on Ampersand Gessobord panel.
Many thanks to Sandy Scott for the reference photo.
