I love these, Adam <3 The first one has a very gothic feel about it (due to the Lucifer roots) and it gives the poster also something.... darker. To see that expression on Batman's face is a confronting thing as a poster, since he's still often seen as 'unflappable'...
The second has a great vibe, also more comic feels, with the pearl necklace and the city rising in darkness within the silhouette of the woman...
Very nice designs, both <3
