Using the provided reference photo, redraw the exact same hiking selfie as a loose hand-drawn sketch illustration. Keep the same composition, camera angle, two hikers, pose, backpacks, clothing colors, cap, rock, grassy hillside, tree line, and snowy mountain placement, but simplify the scene into rough black outlines with marker-and-crayon style coloring, visible scribbled strokes, uneven fills, and a playful childlike travel-journal look. Reduce photorealistic detail, leave large parts of the background as clean white negative space, and make it feel like a quickly colored storybook doodle while preserving the recognizable layout of the original photo.
