Wizard on a Comet in Oil: A Cosmic Voyage

An oil painting on canvas of a powerful wizard riding a blazing comet across a velvet night sky. The scene is rendered in rich, thick oil with visible impasto and dramatic chiaroscuro reminiscent of Baroque masters. The wizard stands astride the glowing comet, one foot on its molten tail, robe billowing, cloak edge embroidered with celestial runes. He holds a gnarled staff crowned with a shimmering crystal orb that pulses with magic. The comet's head is a radiant core of fiery orange and gold, trailing a bright wind of embers and stardust. Surrounding space features distant planets and nebulous clouds in deep blues, purples, and copper highlights. Lighting is cinematic: comet glow illuminates the wizard's face with warm amber highlights against deep shadows, creating a sense of mystery. Painterly textures, thick brush strokes, and subtle glaze layers evoke an epic, mythic voyage through the cosmos. Composition diagonally curves from lower left to upper right, with the wizard gazing forward, signaling destiny and arcane power.
