This whole room is awesome. I especially love the light fixture, shaggy rug, window seat, built in bookshelves, and other organization options. I would add some color to brighten it up and add a long white (corner?) desk to make it my perfect office. I already have visions of lounging in the window seat with my laptop.
If you have a high ceiling look what you can do in that bedroom. Use the top bunk as a indoor tree house for the kids reading nook. Decorate accordingly for boy or girl. Notice the chandelier that has been covered in silk vine. Use camouflage material for a boy's reading nook.
