Start out by visualizing the basic form of Buzz's body. Sketch in basic guidelines.
Lightly sketch Buzz in. F and HB pencils work well for this.
Start defining the lines. A B mechanical pencil was used for this step. Try to divide the body into sections. Work from top to bottom.
Move down the back and chest. Erase away any unneeded guidelines.
Define the arm lines. Thicken and redefine the outline of the entire figure.
Carry the shading in section. A B pencil works for dark shading and a 3H for light shading.
Progress down the back and chest with the shading.
Finish up the drawing by shading in the arm and cleaning up the drawing.
