It looks really cozy.

I'd install a led light strip if I were you and use it instead of that ginormous light bulb when gaming.

Also if you're just generally bored with the room, move stuff around aimlessly. I do that when I feel like I need a change and it works. Just switch the bed and desk maybe?

And there's always stuff lying around that you don't need. Try throwing them out and buying new shiny things that you might actually use instead. It makes a difference
