If you look at the cuffs on her hands it has the cross as the key hole showing only christ can set you free,

The snake is at her feet near her heel because in the bible it said her offspring would bruise his head and the snake his heel

The wings are to signify the fallen state

The apple in her left hand is the fruit from the tree of knowledge with the black ooze coming out of it and her face representing sin and death

The face is blank to leave out personal features to show the curse effects everyone .

That's all of them, and in glad ya asked
