Create a raw candid vertical iPhone night photo with subtle motion blur and harsh warm phone-flash illumination. The scene shows {argument name="character description" default="a 35-year-old sun-kissed European man with tousled brown hair, light stubble, athletic build"} sitting on {argument name="horse description" default="a white-gray horse with a dark leather bridle and saddle"} in a dark wooded outdoor setting at night. He is caught mid-laugh, looking off-camera to his left toward friends, relaxed and charismatic, holding the reins with both hands. He wears {argument name="outfit" default="an open off-white linen button-down shirt over a textured cream knit T-shirt, blue jeans, and a wristwatch"}. Compose the rider centered slightly right, with the horse head cropped large in the lower-right foreground and the man’s torso fully visible. In the lower-left background, include exactly three seated friends near a small campfire: one person in a pale shirt, one blond man in a dark shirt, and one darker-haired man behind them, all softly out of focus and lit by firelight. Include exactly two main light sources: a warm campfire with a small grill grate and glowing embers, and a bright vintage lantern near the bottom edge. The background should be almost black with faint tree trunks and foliage, smoky haze drifting near the fire, high ISO grain, imperfect exposure, natural skin texture, candid party atmosphere, no posed studio look, no text, no watermark.
