Step 15: Use the angled lines on the right to draw the bird's other leg the same way. First use the initial short lines as guides to draw the great horned owl's first two toes. Then draw the two other toes on the right by using the first two as a template. Use curved lines for the talons. You can make the talons bigger if you'd like. Now use the guides to draw the rest of the leg. Don't overlap the lines of the leg in front.
Step 16: Darken the top line to the left of the head to create the top of the bird's wing. Near the middle of the line, draw a small arc for the feathers found there. Add a thin arc at the tip of the line as well for the feather found there. Inside the shape, near the top, add another long line to give the wing more structure. Use the line on the right as a guide to draw the top of the great horned owl's other wing on the right the same way. Add the feathers in the middle and at the tip. Make them smaller because of the angle.
Step 17: Use the curved lines below as guides to draw the bottom edge of the owl's wings. Simply follow the path of the guides and draw a series of thin, short arcs for the feathers along the way. This process is slow, so be patient and take breaks. This section will be sped up so the video won't be too long.
Step 18: Use the shapes below the head as guides to draw the owl's body. Add a series of quick, short strokes along the outer edge of the guides for the feathers. Add a few more strokes within the shape of the wings for extra detail. These strokes should create long, curved lines inside each wing. These lines represent the rows of feathers within the wings. These lines don't have to be exact. Just draw a few curved lines inside the wings.
Step 19: Use the shape at the bottom as a guide to draw the great horned owl's tail. Darken the guides but draw a series of short arcs along the bottom for the feathers. The tail is behind the legs, so don't overlap those lines.
