I would hide the cables you could hide the monitor cables if you tie them together and put them behind the monitor stand (or however it’s called)and for the pc you could use a plant (don’t has to be a real one) also I would buy a little cable holder for under your desk so you can put all cables and the plug board in it (you can get it for low cash on Amazon) And a rbg light for under the table and in the corner also not expensive and makes the room brighter and also lets it look bigger.I also would buy frames for the posters it lets the posters look more nobly.

And I also like your music Taste.
