Goat Anatomy Sketches

These two sketches were drawn with a Tombo marker and a Pigma brush pen from Ellenberger's "An Atlas of Animal Anatomy for Artists."

I drew both of these images across a spread in my sketchbook.  I first used the Tombo to make small marks to indicate the large shapes, the black linework was sketched in after that with the brush pen.  I finished up by adding in value with the Tombo again.  Overall it took me about 90 minutes to draw both the musculature and the bones of the roe goat.
