First point: I don't mind the length of posts as long as it isn't fluffed artificially. What I mean to say is that you aren't bringing yourself to write a long post. I don't care much for a required post size. Always saw those as demanding, especially when much doesn't need to be said. And I also tend to get to the point when I write. As for reading, I could do that all day. I'm fine with that. 

Second point: I liked it. At first, I was confused, but your latest post cleared all of that up. My only point there is to open with it when a new setting is introduced. 

Third point: When it comes to two possible love interests, it always pays forward to make them different from one another. You've been doing a good job of that. Don't beat yourself up if they actually agree on something. It would be rare, but it happens. Speech patterns should not matter too much, though I imagine Rose paying incredible intention to what words she uses while Amalthea, as you said, is more blunt with being vocal about her thoughts. As for mannerisms, all I can really say this early on is that Rose really does like prostrating. 

Fourth point: I saw it as funny, Solomon would too.
