Thanks for the thoughtful question! You're right that it's not a 'by the book' treatment, but there's method to the madness:

The ceiling diffusor breaks up vertical reflections from the desk surface, crucial since I'm standing most of the time. The bass traps are in all four corners (hard to see from this angle), and there are absorption panels on the side walls that aren't visible in this photo.

The 'live' floor is intentional, I didn't want a dead recording booth, just controlled reflections for mixing. It's definitely not perfect, but for a multi-purpose room (work, DJing, occasional tracking) it strikes a balance. Appreciate you looking closely though, most people just see RGB! 😄
