How can this build be improved?

Greetings. My partner built a small room for an upcoming project, which will be a horror type story-based game.

As I’m not a professional builder myself, feel free to give any feedback!

Excuse me, I acknowledge this is all with the right intentions but you’re actually breaking the rules:

You’re breaking MRR2.
Don’t worry. You only get a verbal warning (from me) and I made that mistake on my first post.
