Create a minimalist Halloween t-shirt design that features a silhouette of a witch flying on a broomstick against a full moon, surrounded by bats. The design is rendered in traditional black, with the moon in a soft orange hue, creating a striking contrast. Below the witch, the text "Spooky Season" is displayed in a vintage-style font, adding a playful touch to the overall design. The simplicity of the composition ensures that it remains eye-catching and suitable for casual wear, while still conveying the eerie charm of Halloween.
