Portrait d'un Dragon Cosmique Rugissant à l'Encre

A dramatic vertical close-up of a roaring cosmic dragon head in side profile, painted in an expressive ink-splatter and sumi-e brushstroke style against a stark white background. The creature features a long sharp horn, angular armored facial plates, a glowing white-green eye, and a wide open mouth lined with jagged teeth. Inside its mouth and throat is a swirling galaxy void of luminous [violet] and magenta nebula light, with glittering stars and dust erupting outward like celestial fire. The dragon's body is deep indigo and black with glossy highlights and iridescent emerald reflections along the neck. High-contrast ink splatters, torn brush edges, and explosive particle effects radiate around the mouth and eyes. Tightly framed, head tilted upward in a feral roar, with no environment.
