Use a pencil to sketch a rough outline first. Draw a diamond shape and then add in the eyes on either side of the diamond. The eyes should be slightly angled and pointed at the ends.
Draw a large circle that will make up the torso and add some rough lines for Venom's arms and legs. Make the arms appear muscular and then add in the curved lines to signify the muscles.
Draw in Venom's hands and feet. Venom's hands are clawed and spider-like, so make sure you shape them accordingly. The same goes for the feet.
Use vibrant colors like black, dark purple and red to best represent Venom's character. You can add texture to the coloring to make the page more interesting.
