I enjoy writing with you, and I really enjoy Cartri so far. Especially how you've developed him lately, growing a little more skilled and tackling some difficult issues. And Daiya really enjoys negging on him.
You posts are well written and eloquent, but I'll admit to finding it difficult to read them sometimes. Most of the time it's paragraph separation, especially when the speaker or tone changes. They would flow a lot easier for this reader if you broke up some of the bigger chunks when it happens, and I see it already happening in your latest posts so maybe you're already on it.
The other thing I've noticed more recently is when you shared your RP preferences in a recent chat, particularly that you enjoy more freedom/improvisation. We've been writing for a while and that's the first time it was brought up, and I realized we approach RPing from different angles. It would help if you expressed this earlier to RP partners, because people want to make everyone comfortable while collaborating on story.
Those are just nitpicks, you're doing great!
