My room

It genually looks so trash even though it has loads of posters on the walls, idk why i dont feel like im in a cool room. Ive literally tried everything and I just cant make it look good anyway, it looks like a clean girls room with punk posters and random stuff dropped on the floor. Im going to buy a new rug and pillows so it matches the vibe(hopefully) and maybe more posters?? Im so helpless and everyones room sems to be cooler than mine, even a random room with grey walls and a few furniture would look better. And its already overdecorated, I was thinking that maybe it can be that the colours dont match or the room is just too big to look like a rocker cave.. i want a different room i feel mine is a shame to have. I will try to make it better, its a working progress still but whatever
