Step 15: Go over the final sketch lines with a pen, marker or any other type of permanent ink. Take your time and be careful when you ink to avoid any accidents. After inking, get rid of every pencil mark with an eraser for a cleaner drawing.
Final Step: Color your brown crab drawing! Use brown lightly for shadows to give the figure more dimension and volume. Inside the body, leave a thin strip blank for highlight on the shell. Color lightly at first and slowly build up to the level of darkness that you like. Lightly use dark red directly on top of the brown and blend the two colors together.
Lightly use different shades of red directly on top of each other, slowly blending them. Use red, dark red, red-orange, browns, oranges and even some yellows to cover the edible crab's whole body. Use lighter colors like orange and yellow for the highlights on the shiny sections of the shell. Use black for the tips of the crab's claws but leave a thin strip blank to represent the shiny highlights. Use black to emphasize the shadows and the groves along the outer edges of the body.
Coloring can be time-consuming, so be patient and take breaks. For an easier drawing, just color everything red. Continue to color using different shades of red and brown and slowly blend the colors together. Use more black to emphasize the shadows and for the joints on the legs. It's a good idea to use reference as you draw and color for a more accurate depiction of a brown crab.
Using a bit of gray and purple, add a cast shadow underneath so that the crab doesn't appear to be floating. Don't forget to pause the video after each step to draw at your own pace.
