Konody observed of the Isleworth subject that "head is inclined at a different angle". Physicist John F. Asmus, who had previously examined the "Mona Lisa" in the Louvre and investigated other works by Leonardo, published a computer image processing study in 1988 concluding that the brush strokes of the face in the painting were performed by the same artist responsible for the brush strokes of the face of the "Mona Lisa" in the Louvre. Asmus found that the head appears to be "tilted forward toward the viewer... consistent with the dramatically shorter appearing neck, which is also a greater angle to the vertical than that of the Louvre painting". Another early review noted that "[the head is tilted more forward and the parting of the hair is exactly in the center, while that of the Louvre picture starts in the middle of the forehead and runs towards the back of the head at an impossible and incorrect angle". Asmus also noted that "the Isleworth figure has a somewhat higher forehead, a slightly wider face, and less of a bulge in the veil over the proper left side of the head". He further noted that "the eyes are much wider set in the Isleworth painting". John Eyre reported Adolfo Venturi, in his early 1920s examination, praised "the beauty of the eye drawing... is the principal portion done by Leonardo together with the line of the mouth".
