Step 6: Draw a curved line to the left of the ear as a guide for the bull's horns. The longer this line is, the longer the horns will be.

Step 7: Draw two lines under the first circle as guides for the front legs. You are learning how to draw a bull that is charging, so bend the legs accordingly.

Step 8: Draw two more lines under the circle on the right side as a guide for the bull's hind legs. Bend the lines in three different places to indicate where the joints in the legs will be.

Step 9: Draw a series of lines that connect the major shapes to form the rest of the bull's body. Draw a long line on the right side as a guide for the bull's tail.

That's it for the initial sketch of the bull. From this point on, press harder with your pencil to get a more defined sketch.
