Theme: 5/5
Story: 5/5
Presentation: 5/5
Writing: 4/5
Creativity: 5/5
Most of what I want to say has already been said by previous commenters, so I'm not going to go in-depth in my explanations as to why theme, story, presentation, and creativity are 5/5. However, I will explain why I gave 4/5 in writing.
To give the non-writing readers some context, in writing historical fiction (or historical fantasy) the author always has to balance carefully the tightrope battle between clarity, brevity, and being understandable to modern audiences versus congruence with the established setting. While for the most part the writing is successful in balancing this regard, it does err too far to the latter's side once in a while, especially in the beginning, where I had to reread a few sentences because of their odd structures.
