These minibooks looks so beautifully made, I hope they will take off soon, especially since no one else is making them in Romania.
I don't do tik tok, but have you posted a time lapse of you making a minibook? Personally, I love to see how things are made and that makes people appreciate the process involved. Also, what about promoting in online book forums? Maybe not a direct promotion as you may get kicked out, but adding a photo of the real and minibook to your review, and your website to your bio.
And finally, size matters. People like mini things, they're cute. Perhaps you can consider doing a smaller version as well. Not 3 times smaller because you'd probably lose the image quality, but even half the minibook would make them a lot cuter especially for the female market
Good luck!And don't give up just after a week
