Single Pale Beige Horned Viper

From directly behind, a single pale beige horned viper, its spade-shaped head adorned with a single upright scale horn, its body covered in moderately keeled scales and ending in a short tapering tail, is cast in a crisp cool twilight hue by side lighting from the left that creates selective illumination within a low-key dark scene, all dramatically set against a vibrant aurora borealis or australis where the dancing green and pink lights inform a symmetrical design that thrives on complementary colors for vibrancy.
