I love the way Batman's mask is incorporated into the M. The large, bold letters and dark background feel appropriately sudden and mysterious. The little Batman mask melds right into the rest of the darkness (He is the night).
The black and white look refined, but I sort of wish there was more colour.perhaps wine colours? The glass element in the W is, of course, fantastic. Part of me wishes the text was thicker, though perhaps that would take away from the glasses.
