Step 10: Use the long, sloping line on the right as a guide to draw this reptile's top jaw. Darken the initial guide but make the line a bit more wavy for a more organic feel. Dip the right side down a bit. The left side should stretch all the way to the left edge of the initial circle. Lightly sketch another sloping line on top for the top edge of the upper jaw. Keep the shape thin except for the right side that's a little wider. When you get the snout right, darken the line. Male gharials have a bulbous protuberance at the tip of the snout. Draw this using short, curved lines. Use short strokes along the bottom of the nose bump to show that it connects to the snout.
Step 11: Darken the initial guide on the bottom for the first part of the gharial's lower jaw. Make the line a bit wavier as you darken it. At the bottom, lightly sketch another horizontal line to make the shape thicker. Make the left side of the jaw wider. When you get the shape right, darken the line. Stretch the lower line to the left of the initial circle and curve it up for the fish-eating crocodile's powerful jaw.
Step 12: Draw a series of small, V-shaped lines along the bottom edge of the top jaw for the teeth. Vary the size of the teeth a little, but overall they shouldn't be too long. Make the ones near the tip longer. Inside the lower jaw, on the left side, draw a couple of curved lines for the tongue and throat opening. Draw a series of small, triangular shapes along the lower edge of the jaw for the first part of the teeth. Continue to draw the gharial's teeth along the top edge of the open lower jaw. Space out the teeth; don't draw them too close together.
Step 13: Draw a few short lines under the eye for the texture on the skin. Stretch the lines toward the left for the textured detail on the fish-eating crocodile's head. Add a curved line over the eye for the exterior. Draw another curved line over that for the eye on the other side of the head. Connect the eye to the snout. Draw a sloping line to the left for the flat top edge of the gharial's head. Use the edge of the initial circle as a basic guide to draw the flat head.
Step 14: Use the angled line in the middle as a guide to draw the gharial's first front leg. Follow the basic path of the guide and draw the shape of the leg around it. Sketch lightly at first so that it's easy to erase if you make a mistake. When you get the shape right, darken the lines. Use curved lines for the folds and creases on the skin at the top and middle of the leg. Draw a series of small, V-shaped lines along the bottom of the guide for the digits. Draw the reptile's digits on top of each other so that they fan out around the foot.
