A masterfully refined interior scene set within a classic, high-ceilinged Parisian apartment, captured in the unmistakable "Ligne Claire" style of André Juillard. An elegant woman with a sophisticated, calm demeanor sits by a tall, arched window, deeply engrossed in a book. The line art is characterized by extreme precision, featuring uniform, clean, and continuous ink outlines with no broken edges or sketchy marks. The composition is perfectly balanced, adhering to classical golden ratios. The color palette is composed of flat, muted washes—sophisticated deep blues, soft dove grays, and warm creams—applied with a delicate watercolor texture. Lighting is diffused and natural, emphasizing absolute clarity, narrative stillness, and a total absence of heavy cross-hatching or gritty textures.
