What a tale of love's sacrifice! The art is just gorgeous; you really portrayed Snape's distress so well, his frustration at not being able to have the one he wants, stymied by the morals of the times, and my favorite panel is the one where Harry sits with his wedding dress, thinking over what he's about to give up and become, for love.
The poetry text on the panels is so well-chosen too. Both you and gingertart50 laid it out so well--how literally impossible it was for same-sex couples in that century. Nailed those genres and prompt, too, Snitch! What a classy entry!
