Don't you dare! Really, Kumada, if that's the best criticism I could come up with, you ought to be really proud of yourself. It DOES fit with the antique faerie aesthetic.
It is worth mentioning: my complaint was not that I don't like it, it's JUST that it's on every single page. If you ever do a new layout on this, I humbly suggest you consider finding a second or even a third border. Use them as visual signals that the kind of information you are about to present on a page is a different KIND of information. This kind of visual signal helps people find the information they're looking for at a glance, is all.
If you never do a new layout on this then just leave it as is. It's still very beautiful.
I'd actually planned that for my original layout, and it ended up feeling kind of jumbled in its implementation. I have a whole folder full of public domain page borders from the attempt, and I just couldn't get it to work. Using the same page border gave the book a kind of a throughline, and then I used the seasonal photographs to indicate changes of content and tone between sections.
