Step 6: For the rabbit's eye, draw a circle above the area where the two lines intersect. Draw another circle inside it for the pupil and shade it in.
Step 7: Use the front of the egg shape as a guide and draw in the rabbit's muzzle. The nose is essentially a V-shaped line, and the rabbit's mouth is a line underneath it that splits off into two.
Step 8: Draw a few whiskers on the rabbit's muzzle for detail. Use quick, short strokes to draw them in.
Step 9: Tighten the shape of the rabbit's ears. Using the initial shape as a guide, flesh them out using quick, short strokes. Draw more lines within them for a furry look.
