Everything is just so perfect here. Absolutely EVERYTHING.
I especially love Lutece masks. They remind me a great deal of death masks - although they still tie in with Songbird and a predatory nature vs. Booker's rabbit. I love all the little details here. Booker's hand bandage. The way he pushes Elizabeth against the wall ever so discretely. The light and dark aspects...the confetti-esque overlay...the staircase (which reminds me so, so much of Gatsby and makes my heart sing). And that Batman lookalike in the background ftw. Just utter perfection.
And, as another commenter pointed out - the expressions! Even with masks, you can read them clearly and it's so beautifully real. Gah. So much love for this <3
