Step 30: Use the shapes on the left as guides to draw the other leg and knee protector the same way. This knee protector is facing left, so angle the shape outward and add the detail inside.
Step 31: Darken the outer edges of the shapes under the knee to create the top of Thanos' other boot. Draw an angled line under the knee for the design element inside the boot. Darken the rest of the initial guide and add a heel to the boot. Add a series of lines inside the shape for the design elements.
Step 32: 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 Thanos, get rid of every pencil mark with an eraser for a cleaner drawing.
Final Step: Color your Thanos drawing using color pencils, markers or crayons! Use violet or purple for the skin. His skin can range from pink to purple , depending on the light. Add some blue to create shadows. Use dark blue for the main part of the shirt. Color lightly at first and gradually build up to the level of darkness you like.
Use yellow-orange for the gold trim on the shirt and the gauntlet. Add a bit of light brown to the trim on Thanos' shirt and infinity gauntlet. Use dark brown for the pants and brown for the boots. Remember to start off coloring lightly and slowly build up the color. Use a bit of dark brown to create shadows on the infinity gauntlet and shirt.
Starting on the left, use orange for the soul stone, red for the reality stone, blue for the space stone and purple for the power stone. Use green for the time stone on the right and yellow for the mind stone in the middle.
