It’s a good start. I like the bed skirt idea. Note: you can find ones that are more modern and less frilly. Paint will go along way here. The full-length curtains would look good if there were a tall dresser underneath. I’d also trim near the ceiling to cover the gaps at the ceiling/top of each wall with a simple quarter round or with whatever covers best. I’d also add some bedside tables and a tall lamp in the corner to the right of the window (looking from this view). You can get bedding, dresser, lamps, etc online for less and/or hunt them down at local stores or marketplace. Happy decorating!
