[구도의 문법] 대각선

Strong diagonal composition: a steep outdoor concrete staircase at night with a glowing magenta handrail light running in one straight line from the exact bottom-left corner to the exact top-right corner of the frame, the steps and wet surfaces arranged along that same diagonal, a single small figure climbing near the upper third. Nothing horizontal or vertical dominates. Cyan shadows, dark sky. No signs, no text, no letters, no logos.
