This coloring page features an intense battle between Spider-Man and Venom. Venom is huge and has sharp teeth, and is trying to bite Spider-Man. In response, Spider-Man is trying to web Venom's maw shut. To make this scene even more dramatic and exciting, I would color Venom in shades of purple and green and make sure to emphasize his sharp teeth in darker hues. I would also color Spider-Man in bright red and blue to really stand out against Venom. Lastly, to really make their battle come alive, I would give Venom's webbing a bright yellow color and emphasize its streaks and curves with more vibrant hues.
