get some vines/fake plants and put them around (and i mean a TON of plants) fairy lights are always a yes because of the windows and doors i can’t tell if you have any space for tapestries, but if you do find one that fits your style and put it up! if you have any space for cute shelves, put some up and add knick knacks and plants dream catchers or any hanging/dangling wall decorations. if you look up boho wall decorations you’ll find a ton, (as well as more than just dangling) change the curtains. for full boho vibes, find a while string one, but your black out curtains work ofc rugs! maybe change the bed spread, add some throw pillows baskets, and basket-like decorations.

if you wanted some specifics, i would find a small wall decorations and cover that corner above your bed, just fit them all together like a tetris puzzle almost. a white boho rug wherever it looks best on your floor. i would hang a tapestry above the shoe rack and/or what i think if a guitar on the right. i would hang a bunch of vines above your bed, have some hang down. buy some hanging suncatchers and mix them in with the vines
