Compelling pic, really evocative of the ambiguities of the Snarry relationship.
I really like how everything is either black, white, or shades of gray. It really throws the focus on the only color in the picture, the men's faces. The shadows partially obscuring the moon are ominous, but in a way, provide a little protection against detection by others (enemies or friends who may not understand?)
The expressions are masterful: intense, incandescent, determined, almost at cross-purposes. Severus wants Harry to leave him to his fate, and Harry wants Severus to allow him to help.
Thank you mystery artist, for a dark, yet uplifting work!
