Step 6: Draw four lines under the body (two below each circle) as guides for the horse's legs. The front leg on this side will be raised, so the line has to bend. Pay attention to the shape and length of this line. The end result should be similar to the number 2 or letter Z on its side. The line for the horse's front leg on the other side should have a diagonal orientation but still bend near the middle a bit.
The line for the horse's hind leg on this side should start inside the circle and have a vertical orientation with a slight bend near the bottom. The final line should be straighter than the others and should have a diagonal orientation.
That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.
Step 7: Lightly sketch the horse's eye inside the head on the left side. The shape should be similar to a flat football. When you get the shape right, darken the lines. Shade the inside of the eye except for a tiny circle off to the side to represent glare. Add an extra-dark value to the middle of the eye for the pupil. Add a curved line at the top for the eyelid and a line at the bottom for extra detail. Add a couple more lines around the horse's eye for the wrinkly skin.
Step 8: Draw the horse's nose near the tip of the initial arc shape. First draw a curved line, then shade to the left of it for the nostril's opening. Draw a few more lines around the nostril to indicate the nose's structure.
Step 9: Draw the rest of the horse's muzzle using the initial arc as a guide. Follow the basic path of the arc as you darken the line to create the front part of the muzzle. Curve the line inside the head, under the nose, to create the mouth. Draw a curved line under the mouth, while still using the initial arc as a guide, to create the chin. Add a few lines around the mouth for extra detail.
