Enchantment Tower on my forever world!

I've made a separate building just for the enchantment room on my forever world. I wanted to make it an actually interesting and special part of my base.

The little mountain/hill the towers sits on was too small so I dig it down and custom made it from the bottom.

It was my first tower of that scale and I have no idea for how to make "aesthetic" interiors, hope you'll like it ^^
