Observational Drawing Odd and Ends

These were sketchbook assignments for Observational Drawing. For those who might not be familiar with the art world, one of the most common forms of practice is to copy master works. I've been assigned a few for this class. The first is my copy a Da Vinci sketch (Thanks to Bob Cole for the book it came out of!) The second is my copy of Jacques-Louis David sketch, (David actually was doing this practice sketch after Michaelangelo!) The last is my own rendering of a bunch of vegetables we had in the house.
