This is a much cleaner version than some pirated ones that were floating around right after Wonder Woman came out.
Two things of note:
1. There's a remarkable array of DC characters (heroes and villains) there in the broad shot — it's fuzzy, but some obvious ones to spot (beond the ore JL): Black Lightning, John Constantine, Atom, Batgirl, Braniac, Hawkman (and Hawkgirl), Shazam, Supergirl, Firestorm, Nightwing, Mongul, Harley, Joker, Luthor, Black Manta, Solomon Grundy.
2. Okay, I get it that these are the comic book versions of these character (it appears). But given you have a DCEU Aquaman that is already showing up in trailers and publicity stills, it might have made sense to include someone looking more like him here, rather than the blond-haired orange-and-green-garbed classic.
Notably absent is the Inferior Five.
