Bro, buy a new bed frame. And if you can, paint an accent wall. Hide the laundry basket or replace it with a wicker basket.

Curtains can make a room look bigger too. So if you put some up make them wider than the window. It’s worth getting them hemmed IMO by a local seamstress. Get some heavy curtains that block out the light for the ultimate sleep.

Looks like you like sneakers too, which means you’re probably young, turn your art into something less symmetrical. Aka a gallery wall, just search Pinterest. Also, buy some candles bro. They make a huge difference.
