In general, I agree with your post, it's a good suggestion. But I would like to clarify something.
We have a quest with an artist or the opportunity to order a statue. It would be much more logical. It's enough for them to add Astarion's reaction to this quest.
Astarion, judging by his phrases, loves drow and is not afraid of them. But I would like more answers with the drow tag for Astarion, because he is an elf.
I would generally like to see the opportunity to play as monogamy character... Give me phrases where I can say that my partner is important to me.
You can get a confession scene without a blood dealer and it actually looks more natural. The problem is that it starts not from relationships, but from the course of history.
A big plus to gossip about relationships. In general, I would like the companions to communicate with each other more often.
We need more information about the ritual. I don't care if it's a piece of paper or something, at least something. Raphael's words are not enough for me. You introduce such a serious thing into the game and there is almost no information about it.
I want you to notice that after Ascension, all the player's dialogues are negative or stupid. The dialogue after Ascension should be reworked, especially the answer to the question "what do you want". I should be able to answer "nothing" or "to make you happy" or "to be with you." I find the options "your body" or "being a vampire" strange. The other two options are negative and aggressive.
You can also breakup with Ascended Astarion in this dialogue and the next scene in four different ways. Do you know what I want? So that you can breakup with spawn. You can't leave the graveyard scene. You can't say to Astarion, "No, I'm not going anywhere with you." It's not fair. Why can't I say no to him? I literally can't give up the graveyard scene. it's very strange.
You see how the writers treat your character. If you have made Astarion a spawn, then you cannot respond to him as an evil character. If you have a relationship with Ascended Astarion, then you do not have a neutral reaction to his behavior. It's as if you're a disgruntled kind character again, or a stupid evil character who doesn't care about Astarion.
His scenes after the ritual are devoid of rolleplay.
