Brown Calf and Cow ink sketch

5x7 ink sketch using black Tombow brush pen on Strathmore Bristol 400 series, doing only dark areas first, then using a rigger brush with water for grey midtones.  I used one of my old photos taken at my mother's west Texas farm in the late 90s.  The calf was brown and the cow black.  This was done today and already posted in WetCanvas! Southwestern and Western forum in the Sketch Thread, where your work cannot be longer than 1 hour; my time was less than 30 minutes.  I was captivated by the shadows as well as their bovine shapes.
