What do you notice?
Look at these two figures.
Left: a nymph from Bouguereau's Nymphaeum, 1878.
Right: his Venus, painted a year later.
Bouguereau reused his own figure.
He took that nymph, enlarged her, made her hair longer and lighter with a more intense sway. He recycled his own perfect figure and made it divine.
A good pose was too good to use only once.
