[bumble bee]

The lavender gown is symbolic as the Victorians wore this color as they came out of mourning after wearing black. The snow is thin and the angel has cups which hold blood - the promise of new life.
Its like its represents the transition from death or winter the dormant and dying season to the promise of spring and new life.
I can almost envision the angel performing a ritual with the blood which causes the change of seasons. Alchemy.
