Step 20: Use the initial circle as a guide to draw the fist. Follow the path of the circle but make the fist smaller and more angular. Add the thumb on the right as a curved line. Draw the folded index finger near the middle of the circle using a series of curved lines. Add another curved line under the index finger for the folded middle finger. Draw Batman's remaining folded fingers using curved lines under the middle finger.
On the top section of the forearm, draw a curved line to show where the glove begins. On the left side of the forearm, draw three diamond-like shapes for the blades on the gloves.
Step 21: Draw the arm on the right side using the initial shapes as guides. Follow the path of the guides and darken the outer edge of the shapes to create the arm. Add a few lines within the shape of the arm for Batman's muscle structure. If you made the other arm wider, make this one wider too. Try to keep both sides symmetrical.
Step 22: Use the initial circle as a guide to draw Batman's fist on the right. The thumb should be on the left this time. Draw it using a small U-shaped arc. This fist should basically be the mirror image of the other fist. Everything should be more or less the same but inverted. Draw the folded index finger near the middle of the circle using a series of curved lines. Then draw the remaining folded fingers as curved lines under the index finger.
Near the top of the forearm, draw a curved line for the glove's opening. On the right side of the forearm, draw three diamond-like shapes for Batman's glove blades.
Step 23: Draw the Batman symbol on the top part of the chest by first drawing a tiny head with pointy ears. On either side of the head, draw a short, curved U-shaped line. On the sides of the U-shaped lines, draw a longer horizontal line for the top part of the wing.
Draw a V-shaped line under the head for the bottom portion of the Batman logo. Then connect the V-shaped line to the side of the wings using two curved lines on each side. This is just one style of the many variations of the Batman logo. You can use a different version if you'd like.
Step 24: Draw the shape of Batman's chest by first drawing a vertical line right across the logo. Follow the bottom edge of the initial oval to draw the pectoral muscles. The pecs basically consist of two long horizontal lines under the logo. Under the pecs, draw two slightly curved, diagonal lines for the rib cage.
