Generate a captivating portrait illustration of a female artist, artfully influenced by the timeless aesthetics of Rembrandt and the modernist allure of Modigliani. Envision the subject enveloped in the chiaroscuro technique of Rembrandt, where masterful interplays of light and shadow sculpt her features with profound depth and emotion. Infuse the composition with Modigliani's signature elongation and stylized simplicity, capturing the subject's grace and allure. Picture the woman in a pose that reflects both Rembrandt's introspective intensity and Modigliani's avant-garde elegance. Merge the classical and the modern, creating a portrait that harmoniously marries Rembrandt's classical finesse with Modigliani's distinctive avant-garde flair, resulting in a captivating synthesis of artistic influences.
