Un démon aux cornes dorées brandit une épée lumineuse dans une œuvre à la craie

A formidable, muscular demon with greyish-blue skin, glowing green eyes, and large, ornate golden horns stands center frame. He is clad in intricate golden armor adorned with emerald green gems, and has large, leathery, dark wings. In his right hand, he wields a magnificent sword that crackles with vibrant green arcane energy, emanating a powerful glow. The background is a dark chalkboard texture, on which the French title "DÉMON AUX CORNES D'OR" (Demon with Golden Horns) is written in colorful chalk, with gold and green chalk lettering for the title. Scattered around the demon's feet are various pieces of colorful chalk and chalk dust, including green, blue, yellow, and white. To the left and right of the demon, stylized emerald gem emblems are also drawn on the chalkboard. The overall art style mimics a chalk drawing on a blackboard, with visible chalk textures and a slightly rough, artistic rendering. The lighting is dramatic, with the green energy from the sword illuminating the demon and the immediate surroundings, creating a mystical and powerful atmosphere. The composition is a medium shot, focusing on the demon's imposing presence. The mood is epic and fantasy-driven, with a vibrant, contrasting color palette of deep blues, greens, and golds against the dark chalkboard. This is a "chalk art" style illustration.
