Portrait in three-quarter close-up, dark fantasy film style, a stunningly beautiful and slender girl with an innocent and naive expression. Her long black hair flows over shabby black knight armor crafted from blued steel. The armor shows the wear of countless battles and is covered by a superbly detailed, tattered dark brown wool cloak with a coarse weave. Behind her, a dramatic background of stained glass enhances the gloomy and scary atmosphere, brought to life by expressive detailing and hyper-realistic textures. Natural daylight filters through, reflecting off surfaces and casting intricate patterns of light, creating a cinematic lighting effect. Her eyes, large and full of wonder, reveal a depth of emotion, while her exposed arms and neck display a subtle vulnerability. The scene is devoid of deformities and distractions, focusing solely on the ethereal beauty and eerie ambiance. It captures the essence of dark fantasy with intricate workmanship and a hauntingly beautiful composition.
