Great start, Wesley! The last time I read anything about Dorian Gray was a long while ago, but they seem somewhat familiar to me, especially Lord Henry's choice of white shirt and grey vest haha.
1. I'm not actually sure if Dorian was actually inclined towards being an arse, but I'll assume that that might've just been added as a game element. I think personality-wise, Dorian is so far almost entirely up to the player. Dorian doesn't say anything you don't tell him to say and because the dialogue is what's driving the two ways you can play Dorian, it seems like I don't have to come into this expecting anything. That said, I definitely like the feeling that Dorian keeps getting drawn back to the painting and its beauty and the little tidbits about Basil's perception. That's very in-character, from what I remember.
2. I can think of making some of the choices a little more neutral. The dressing up part seemed like it was such a big deal at the time but Dorian ends up skipping over it and it's only mentioned by one of the Ladies what he ends up choosing to wear. Would be fun to be able to see him dress himself.
3. Pacing was a little confusing for me, because the progressions between the different Ladies felt abrupt and unsure of where to end up while the conversation with Lord Henry about Dorian not attending the luncheon (if you picked it) felt much longer.
"But I won't cover your ass just so you can save face with my aunt." > Last thing, this line for some reason just took me out of the immersion. It feels too modern, and not that British for the time period, which is where I think this story is from?
