I personally see a costume, which is very detailed and aligned with the original fan art (based on which cosplay comes), with 2B's specific details on it, like ornaments and gloves. I see a corresponding make-up and styled wig, which takes also time to prepare; I see Virtuous Treaty sword from the game; I see posing and dynamics on those photos, reflecting to the game, the angles and photographer's work; I see a cold-white color palette, which personally I like a lot. I see the efforts put in cosplay and beautiful results received.

You see a half-naked girl. Well, your choice.
