Create a highly detailed and atmospheric fantasy scene set in the night

Create a highly detailed and atmospheric fantasy scene set in the night-time streets of Valoria. The streets are uneven, cobblestone-paved, and sparsely illuminated by flickering lanterns. These lanterns cast dancing shadows on the walls of ancient buildings. In the foreground, feature Donovan Black, a mysterious elf clad in dark, leather armor. His armor should blend seamlessly with the shadows around him. Donovan's face is partially obscured by a hood pulled tightly over his head, but his pointed elven ears should be subtly visible under the hood. Donovan is mounted on an elegant black mare, her muscles rippling under her shiny black coat as she gallops at high speed. Include visible breath from both the horse and Donovan in the cold night air. The mare should appear powerful and slightly defiant, yet obedient to Donovan's commands, indicated by the subtle pressure of his legs and his firm grip on the reins. Capture the intensity and determination on Donovan's face as he navigates the labyrinthine streets of Valoria, with a clear sense of urgency and purpose. The scene should exude a sense of tension and imminent danger, suggesting that Donovan is being pursued by unseen enemies, possibly city guards, as hinted by the echo of hoofbeats on cobblestones. Include elements of the surroundings that add to the medieval fantasy atmosphere: narrow alleyways, old stone buildings with intricate details, and a generally dark, moody ambiance. The composition should convey a high-stakes chase through a complex urban landscape, with Donovan’s knowledge of the city’s secret paths as his only advantage.
