Can you afford to change your flooring? Because that’s the first thing I would do. Then, I’d wall mount the tv with a shelf for accessory storage (or buy a tv stand). Change out the ceiling fan for one that’s better looking and more powerful, so you don’t need the secondary ones atop the dresser and nightstand. Add a window AC unit on the longer window if it’s still too hot. Clear the clutter on that one nightstand. Replace your bedside lamp. Assuming you like your quilt, try something in patterned porcelain or milky or clear glassBuy pillow shams that coordinate with your quilt, and a lighter bed skirt. I would take down the curtains and just go with the colored shades. If you need more cover, add lighter-colored curtains (even white) on all windows, fitted to just slightly larger than the window. (I disagree with the suggestions of longer curtains. Your windows are an interesting feature; that would disguise them, and add heaviness to the room.) Add a headboard. Do you still like the art hung on your wall? If not, take it down. If so, move and frame the heart poster (it’s oriented quite oddly for viewing). Add more art to the tv wall. Replace the two blankets with one (or two, if there’s a reason one is insufficient) in the color palette of your quilt.
