The epilogue feels weirdly short, yes. Especially with an Origin because otherwise almost everyone you can talk to at the party seems to have unique dialogue lines for them. With romanced Spawn-Astarion you also seem to be looking for a cure no matter which option you picked, as it is always a discussion topic with Minsc.
I'd like to gift Spawn Astarion the portrait you can get as a quest reward (in case that ever gets fixed). Not just as him mechanically being able to get painted, but as dialogue option you can offer to him.
