Study Tour - Part 2: Book Nook and Bookshelves

Welcome to my cosy book nook! I've always wanted a space like this since I was a child, and it's absolutely everything I could have dreamed of. This wee nook is my favourite place to be. The only thing missing from the space that I'd really like to add is a round, soft rug underneath the chair and footstool as well as rental-friendly wallpaper for the slanted wall (realistically, the latter will probably never happen).
I forgot to mention that besides the cube unit, the bookshelves themselves are shelves that I was gifted by my in-laws (the small ones), and the floor-to-ceiling unit was purchased locally, secondhand.
