Theme: A cozy, autumnal scene where a chic rainbow girl is dressed as a witch, relaxing on a bench with a pumpkin spice latte clipart . Details: She’s surrounded by jack-o'-lanterns, fall leaves, and perhaps her broomstick is leaning against the bench. Add some playful black cats or a cauldron bubbling next to her with magical smoke swirling around. The moon could hang large in the sky with twinkling stars.
