Step 15: Use the remaing shapes and lines as guides to draw the rest of the body. Simply follow the outer path of the initial guides and darken the lines as you go along. Use quick, short strokes on the left side of the body and at the bottom for the feathers.
Step 16: Draw a series of small, curved lines on the top, left side of the body for the curly tail feathers. The tips of the feathers should be pointy, and the lines should overlap one another. The feathers at the top should be bigger, but overall they should be small to form a curly tuft.
Step 17 (optional): For a cleaner look, erase as much as you can of the initial guide lines. Don't worry about erasing all of guides. It's okay to leave some behind. Re-draw any final sketch lines that you may have accidentally erased.
Final Step (optional): Add some shading to your 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.
Add a cast shadow underneath. This helps ground the dodo so it doesn't appear to be floating.
You can add even more value throughout your drawing for extra detail. The dodo became extinct before it was properly documented, so the only remaining references are old drawings and paintings. Therefore, you can shade yours differently if you want. Or you can add a single value all over the body like this. You can separate each individual stroke a bit to get a coarser, more feathery texture. Leave the tail and wing feathers white. Don't forget to pause the video after each step to draw at your own pace.
