Below is a step-by-step drawing tutorial.
The first step is to draw the shapes and guides that will form the frame for the Four Arms. Draw the head shape as a small circle. Next, draw the guide lines for the face. Move towards his fist and draw a small circle. Next, start drawing the lining for some of his fingers. Next, draw the linings of his body such as his torso or legs. Draw the instructions shown from these shapes.
You will now draw his facial expressions. As shown, you will need to draw the shape of his head. Start by moving to the left. Draw the flame-like shape of his left upper arms. Next, draw the lower left arm shape using his fist. You can now shape your left leg and draw the muscular definition. Mark the details of his right arm, foot and right hand by drawing the knuckles of his right fist.
You are almost done, as you can see. Next, draw the details of his uniform on his chest and shoulders. Next, identify the left arm with more muscles. As shown, draw out the lower right hand of the man and then add more detail to his right fist. Move on to the next step once your image is similar to the one shown above.
Here is where you draw and sketch. First, draw ionic homogenous fingers on his left arm and right hand. Next, you will move to the right and draw a uniform logo on his shoulder. You can also sketch details on his arm. You can now erase all guides and shapes you created in step 1.
