Step 6: Inside the dragon's mouth, along the lower edge, draw a series of small, triangular shapes for the bottom row of teeth. Draw two curved lines for the tongue. On top of the head, draw two long, pointy shapes for the horns. Pay attention to how the horns curve. Dragons are mythical creatures, so you can change the horns however you'd like.
Step 7: Draw a couple more triangular shapes on the left side of the dragon's head for more horns. Darken the lines for the neck but extend the shape farther inside the body. Draw a series of small triangles along the top edge of the neck to create spikes. Close to the bottom of the neck, draw a line for the underside of the body.
Step 8: Use the angled line on the left as a guide to draw the dragon's first wing. Add an angled line close to the tail to create the outer edge of the wing. Add a pointy shape on the top, right corner for a spike. Draw the bottom edge of the wing using curved lines to create spiky segments. The resulting shape should be similar to bent triangle.
Step 9: Draw the dragon's arm-like shape that connects to the body using the initial angled line as a guide. Bend the shape and add a spike on the bottom corner. Add a line on the left side to give the wing another segment. Draw the lower edge of the wing using curved lines that connect to the body. Draw a sloping line at the top for extra skin on the wing. This is a wyvern type of dragon, so the wings are essentially the extended arms as opposed to other dragons that have regular arm appendages and wings on the back.
Step 10: Use the lines on the right as guides to draw the dragon's other wing the same way. Add a couple of segments in the middle of the shape using a couple of lines. The middle segment should be similar to an upside-down letter V. Add the bottom edge of the wing using curved lines. Add the top part of the wing using a sloping line above the head. Don't forget to add a small, pointy shape on the top corner of the wing for a spike.
