These pictures of a cat toy were done for my drawing class.

The top one is a pencil drawing and was a study in composition.  We spent a good hour or more sketching out different compositions until we found one we liked.  I liked this one because it is just plain silly… looks to me like the scene of a crime.  There is a cat out there somewhere hiding from the authorities.

The bottom picture was a pen study in shading and line quality.  The gist of the exercise, as far as I can tell, was to demonstrate how lines can be made to simulate shading from a distance.
