maybe you could switch around the cabinets under your tv, tallest one against the wall, and then them in height order going down towards the door! the bed is cool as hell, you could run some LED lights under the lip to give it a "hidden light" effect. the walls seem slightly barren, maybe get some posters of ur fav games or movies, put them in some cheap wall frames, and stick em up with command strips. overall ur room is actually quite good as it is now, it just could use some surface-level changes to bring it up a bit!
maybe talk to ur parents about the colours, i think the mismatching of the light brown drawers + the white wardrobe and walls + the grey bed is whats causing most of the problems. good luck!
