With a name like The Sin it is quite obvious that this is a religious artwork. The question is, if you didn't know the title would you realise it ? When I first saw this I thought it was Snow White. Now there is a war being wages in my mind as the female character switches between the two. I am leaning towards Snow White because the hair makes it seem as if she is falling and her eyes are closed. It seems a brilliant artistic representation of being poisoned by the apple.
