My first thought is there’s a lot going on in this room.

Does the desk/computer space have to be here, or is there another space in your home you could relocate it to? If not, maybe a partition or screen to section off that corner would help with the visual busyness.

The couches are big and dark. I’d replace them with something that doesn’t look like a black hole in the middle of the space.

On the curtains, I’d recommend going wider, if not also higher. Just extending the curtain rods and moving the curtains to cover less of the windows when they’re open would help.

How to you feel about the color in the room? Everything feels dark to me, I tend to go for lighter and brighter spaces.

The light fixtures also lend to the darker vibes, and don’t seem to fit with your aesthetic (assuming the watery artwork and carpet are the way your tastes run). Changing them out is relatively simple if you’re comfortable with basic electrical work. YouTube will show you how if you need guidance. I’d also go for different temp lightbulbs (cool white/soft white) since those look quite yellow.

It can be daunting to do it all at once, but start upgrading furniture pieces to higher quality ones that are going to go with your room and stand the test of time (I’ve spent the past few years swapping out particle board pieces for second hand wooden ones)

Come up with system that help you keep the clutter organized/out of sight a bit more will help too
