Miss Hokusai is a 2D animation with elements of CGI that are nicely textured to work with the general aesthetic. The aesthetic is beautiful, it is heighten with the cleverly used cinematography, such as the awareness of space, differing between deep and shallow focus to make the scene more dramatic.
Storyline didn't have that crescendo however loved the story regardless. I would say that the run sequence near the end would have been the crescendo but in my personal opinion it was more of a desperate action to reach her sister whom she already knew the circumstances, that personally isn't a crescendo as the build up was quite slow, so it was more of a nice but emotional end. The story was based on a person in history but would have been nice to have seen her with her husband at the end, even though they divorce, it still would have ended nicely. I knew that her life wasn't meant to be a happy ending as in reality no one really has that knight in shining armor and she herself wasn't that bothered with romance, her work was her life.
I liked the supernatural additions, it reminded me of Studio Ghibli's approach, in fact parts of the character design and overall aesthetic was approached with that iconic Ghibli appeal. I loved the thick eyebrows, they worked so well for the main character, as well as the fly-away pieces of hair.
Referring back to the supernatural additions, I loved how the dragon ripped from the paper and became a gust of wind. It worked so well and the secondary animation of the paper and characters around it being taken with the wind aided the action.
