A captivating oil painting featuring a purple dragon with heavy impasto texture, its presence exuding an eerie cosmic horror vibe. The scene is set against a starry, otherworldly backdrop, with swirling nebulae casting ethereal glows around the dragon's elegant, intricate scales. The creature's form is masterfully detailed, evoking the sophisticated artstation concept art style reminiscent of Craig Mullins, with creative touches that enhance its majestic and mysterious aura. Minor creative elements, such as luminescent eyes and subtle hints of cryptic runes on its wings, elevate the dragon's enigmatic allure while maintaining the core essence of the artwork.
