Thanks, glad you enjoy it!
It's not an intentional reference, no. I haven't played any of the Persona games before, so any references in that direction are purely coincidental lol
it just looks so similiar, since it has the stairs in the background and even the bucket under the tv with a brown couch next to it, let alone the same flag above the tv.
but since you haven't played the games, how did you make that shot then? was it like a premade art already and you just added your character to it? (sorry for being so curious ;3)
