Step 6: Under each U-shaped arc, draw a small oval as guides for the top part of the forearms. The top part of each oval should be behind the U-shaped arc. Now under each oval, draw two short vertical lines as guides for the lower part of the forearms. Under each forearm, draw a small circle as a guide for the fists. Try to make the shapes on either side of Batman's body the same size so that there's symmetry.
Step 7: Draw a triangle-like shape under the midsection as a guide for the lowest part of Batman's torso. First draw two short vertical lines on the sides, then connect them with a longer V-shaped line. The arcs should start right under the torso and then tilt outward slightly.
Step 8: Under the torso, draw two long U-shaped lines as guides for the top part of the legs. The arcs should start right under the torso and then tilt outward slightly. Sketch the arcs lightly at first, then darken them when you get the shape right. The longer they are, the longer Batman's legs will be. Under each arc, draw a small circle as a guide for the knees.
Step 9: Under each knee, draw a small U- shaped arc as a guide for Batman's calf muscles. These arcs shouldn't be as long or as thick as the arcs for the top part of the legs. Under each arc, draw two short vertical lines as guides for the lowest part of the legs. Connect the short vertical lines at the bottom using an even shorter, curved horizontal line. Now draw the guides for Batman's feet at the bottom using shapes similar to triangles with the top part missing.
That's it for the guides! For the next steps, use darker lines for a more finished drawing.
