Step 20: Use the shapes on the right side of the torso as guides to draw Thanos' infinity gauntlet. Draw a curved line near the elbow for the gauntlet's opening. Darken the sides of the shape. At the top, darken the circle but make the sides flatter for the metallic fist. Make the top edge blockier for the folded fingers pointed away from the viewer. On the right side of the fist, draw a curved line over the folded thumb for the first infinity stone: the time stone.

Step 21: In the middle of the back of the fist, draw a big oval-like shape for the mind stone. At the top of the fist, starting at the left, draw four smaller circular shapes for the soul, reality, space and power stones. Draw an angular shape around each stone for the base on the infinity gauntlet. Space out the stones so that they're close to each other but not overlapping. Darken the guides to the right of the infinity gauntlet for the visible part of the rest of Thanos' arm.

Step 22: Add a few angled lines within Thanos' infinity gauntlet for extra detail on the metal. You don't have to draw every single line on found on the real gauntlet. Just draw a few lines to indicate the detail. It's basically some angled lines on the wrist and forearm , and a curved line near the bottom.

Step 23: Draw a series of short lines around the neck for the shirt's collar. Draw a couple of long, vertical lines below Thanos' neck and across his chest for the shirt's opening. Add a few lines inside the neck for the muscle structure. Draw the part of the shirt behind the infinity gauntlet.

Step 24: Use the shapes in the middle as guides to create the torso. Darken the outer edges of the initial shapes all the way down to the leg because the back of the shirt is long. On the right side, near the bottom, draw an angled line for a design element on Thanos' shirt. Add a couple of angled, horizontal lines across the bottom of the torso for the belt.
