Your art's very good, and, most importantly, not a bog-standard webmanga style. The text's a little tricky, but you get used to it pretty quick, and it does have a kind of "floaty" feel, as you said.
Writing can be a little odd, at times- wotsername instantly understands what a "cook" is, even though no-one there cooks, and she bothers to explain that they're nocturnal, as if it wouldn't be taken for granted. The way she explained magic seemed a little odd, too, and seemed more like a tutorial from a video game. It sort of seemed like the characters were role-playing, or something, and wasn't as natural as it could be (I don't know if any of that makes sense).
Still, very good overall.
