Step 15: Use the angled line on the left side as a guide to draw the hind leg the same way. Draw a series of short, curved lines around the guide to create the shape of the gharial's leg. At the bottom, draw short, curved, V-shaped lines for the digits. Spread out the toes and draw lines between them for the webbing. The crocodile's other hind leg is not visible from this angle, so don't draw it.
Step 16: Use the shapes in the middle as guides to draw the rest of the gharial's body. Simply darken the outer edges of the initial guides to create the shape of the body. As you darken the edges, use wavy lines to give the body a bumpy texture. Use the last angled line under the body as a guide to draw the other front leg the same way as the other legs. Most of the leg is hidden behind the body, so just focus on drawing the small, V-shaped digits at the bottom. Draw a row of short, angled lines across the middle of the body and into the tail for the detail on the rough back.
Step 17: Darken the initial guides on the left side to create the tail. Continue to draw the line for the top edge of the body toward the left across the fish-eating crocodile's tail. When you get to the top edge of the tail, draw a series of small, triangular shapes along the line for the tail spikes. Make the spikes smaller near the tip of the gharial's tail. Darken the bottom edge of the tail too. Add a few spikes along the left edge of the tail that meet with the spikes inside the body.
Step 18: For a cleaner look, erase as much as you can of the initial guide lines. Don't worry about erasing all of the guides. It's okay to leave some behind. Re-draw any final sketch lines you may have accidentally erased.
Final Step: Add some shading to your gharial drawing for extra detail. As you shade the snout, don't overlap the teeth so that they remain white. Use a medium value for the body. Use a darker value to create shadows. Pick the direction of the light source so that the shadows are consistent with it. For a more detailed guide on how to shade, check out this tutorial: How to shade.
Add a few wavy lines at the top of the fish-eating crocodile's body for more detail on the bumpy back. Use horizontal strokes as you shade. Use curved, vertical strokes on the side of the body to indicate the scales on the skin. Don't shade too smoothly. The rough value gives the skin a bumpy texture. Make the shadows darker. Vary the pressure on your pencil to get different degrees of tonal value. Shade lightly at first and slowly build up to a darker value. It's a good idea to use reference as you draw for a more accurate depiction of a gharial. Shading can be time-consuming, so be patient and take breaks.
Add a cast shadow underneath. This helps ground the gharial so it doesn't appear to be floating. Don't forget to pause the video after each step to draw at your own pace.
