Step 15: Draw the rattle using the tip of the initial line as a guide. The rattle is made up of many tiny wavy lines sitting on top of each other. Follow the path of the guide line as you draw the rattle. The wavy lines for the rattle should get smaller the higher up they go.
Step 16: Erase as much as you can of the initial guide lines for a cleaner look. Don't worry about erasing all of the guides. It's okay to leave some behind. Re-draw any final sketch lines that you may have accidentally erased.
Final StepAdd some shading to your rattlesnake drawing to give it more dimension and volume. Pick the direction of the light source when shading so that the shadows are consistent with it. Vary the pressure on your pencil to get different degrees of tonal value. Continue adding the value until the entire body has the appropriate shadows.
Add a cast shadow underneath. This helps ground the rattlesnake so it doesn't appear to be floating.
You can add even more value throughout your rattlesnake drawing for extra detail. Alternate between a light and dark value to give the rattlesnake a diamondback pattern. The key is pressure control with your pencil. Push harder for darker values, then push softer for the medium value. Start adding the diamond-like shapes with a dark value until the entire backside is covered. The diamond pattern wraps around the body, therefore only part of each diamond shape is visible from this perspective. It's okay if the diamond shapes aren't perfect. The small imperfections make the skin pattern more organic. Leave a very light border around each diamond shape as you add the value to the rest of the body. Shading can be time-consuming, so be patient and take breaks. It's always a good idea to use reference if you want a more accurate drawing.
