The reference of the first painting, the nude, is nu lisant by Isaac Israëls (near 1900). The reference of the second painting, the portrait, is la liseuse by Auguste Renoir (1876): the original painting could be observed at Orsay museum in Paris. Here is my interpretations of thsese famous paintings with acrylics, as studied at l'ESAD.
