To wrap this guy up, draw the hooves beneath the shaggy fur of the legs. The hooves are round, but have a V-shaped cut in the center. To achieve a three-dimensional effect, first take a triangular cut out of the bottom of the hoof. From those two points, draw lines upward and have them meet at the top of the hoof. Connect these two triangular shapes with a straight line, and now you have a nice cleft in your hoof :) Use rugged lines to draw the rest of the hooves. With this, the main drawing is done. Add some clumps of hair here and there. Draw some pores and spots on the Tauren's nose and face. Add detail wherever you feel it's necessary, but don't get carried away. It's easy to kill a drawing by adding too much detail.
