The thing that gets me about Kaoru Mori is that she doesn't just have impeccable detailing skills and an insatiable thirst for historical accuracy. She also knows when to keep things simple.
No doubt she could have filled in the entirety of this page. Every pebble and pothole, every ornamental plant. But the emotion demands less, not more. A gesture at lace, the swoosh of ruffled petticoats, and a blank void to the left hand side, because all Emma really sees is William, and all that matters in that moment is the two of them together.
It's most noticeable with her faces, I think, which she keeps extremely simple in contrast to the lush detailing of fabric and furniture. Which can sometimes lead to a lack of diversity, but which also means that emotions gets communicated so impressively and effectively.
