Add a smaller hiker in the background on the left side of the rocky slope, below and behind the larger hiker. Show the person at a natural distance and scale, wearing outdoor hiking clothes with a backpack, standing on the angled rock surface. Match the body position to the slope so the person looks balanced on the terrain, and add the natural dark contact shadow around the feet and any subtle shading from the backpack. Match the sunlight, rock texture, color, and perspective so the hiker blends naturally into the mountain scene.

Position a second hiker further back on the rocky mountainside, placing them on the left portion of the slope at an appropriate distance behind the main figure. This additional person should appear naturally scaled according to their position in the scene, demonstrating proper perspective as they stand lower on the inclined rock face. Dress this background hiker in appropriate outdoor gear including weather-suitable hiking attire and a properly fitted backpack that matches what you'd expect to see on a mountain trail. Carefully adjust the hiker's stance and body positioning to reflect how someone would naturally balance themselves on the angled stone surface, ensuring their posture looks authentic for navigating steep rocky terrain. Pay close attention to creating realistic shadows beneath their feet where they make contact with the rock, as well as any subtle shadow effects cast by their backpack onto their body or the surrounding stone surface. The lighting on this background figure should perfectly match the existing illumination in the scene, maintaining consistency with how the sunlight hits the rocky landscape. Ensure the texture and coloration of the rocks around the new hiker seamlessly blend with the established mountain environment, while keeping the overall perspective accurate so this additional person appears to naturally inhabit the same three-dimensional space as the rest of the composition.
