Master Copy: Jean Auguste Dominique Ingres

central figure of "Study for Roger and Angelica", c. 1818; source: Romanticism book by Jean Clay

That book kicks so much ass.
Now, on to the copy. The thing to remember about Ingres is it's all about modulating the contours. Most of his work is lit very flatly, and the form comes primarily from the way he carefully treats his edges. So, go back and take another look.
