Should I start a new Art Book?

I could update the description, cover, etc. of this book but honestly, I love how this book is currently such a nostalgia trip for me, whenever I flip through the chapters and everything else. Filling it up completely and keeping it the way it is seems like a good thing to do.
But in its current state, it gains little to no new viewers. So starting a new book also seems like a good (maybe even better) thing to do.

So, should I keep posting here (the more emotional choice) or should I start a new book (the more logical choice)?
