מחקר צביעת אנימה: סגנון אנימה שטוח עם תאורה כיוונית

A prompt focusing on achieving a specific flat anime coloring style with directional lighting control. It compares a standard flat style (color, flat shading, one shadow level, general highlight) with a version that explicitly defines the light source direction ('light from the left') to achieve a larger, more defined highlight area.
