An 18-year-old woman pausing on a log along a forest trail in the Pacific Northwest, mid-hike. Brunette hair in a shoulder-length bob. Wearing a loose light blue tank top, tan hiking shorts, and a grey lightweight jacket tied around her waist. Loosely holding a plastic water bottle in her right hand. She's glancing up at the camera with a warm, relaxed smile — a candid moment of rest. Dense green foliage and tall old-growth trees surround her, soft diffused light filtering through the canopy. Shot from slightly above. Natural skin texture, visible pores, subtle imperfections — no retouching. Natural colors, photorealistic, soft depth of field.
