The Northern Bobwhite Quail sketch was done using colored pencils onto card stock. The actual Northern Bobwhite gets its name from its call, a whistle that sounds like "BOB - White". It lives in Mexico, the USA and Carribean and is one of the most populous quails in North America.
I added many layers to the background: shadows, texture and text. I played around with some brighter colors, like blues and greens, but ultimately decided on browns and golds, all already in the color scheme from the quail itself.
