very cool and creative game, love the artworks and style ,
i know you're alone making this game but in my opinion, i find the dialogue with each character too similar and too repetitive (listening to her, they take pictures or asking pictures or "what are you wearing"), i think the event in the first game with darla is a very good idea we don't expect it so it's break the routine and make the game more exciting and interesting (sad it didn't continue), also ellie was a good idea too but the relationship seems unrealistic, it's escalating too quickly.
So in my opinion i would say:
keep doing more unique and singular way to get or received picture of a character
make events that you don't expect
and maybe try give more importance to the choice of dialogues
the game have a really good potential, keep going and stay creative :)
