Oh, this is lovely! Both poses are very well executed: I can "see" the twist of Severus's body as he has turned on the bench to face Minerva and contemplate the hovering Felix Felicis, the last wisps of his hover charm curling from his wand. Minerva's lovely, too - all rapt attention and yet relaxed. The light spilling over them from the potion is a brilliant touch. Beautiful!
