I read the other responses, but this is what I would do... I would change out the blue color, maybe a limish green or a blue than is more similar to the blue in the bottom butterfly wings on the quilts or the background in one of your pictures. Obviously, not that bright, but more in that color tone. Painting the trim would make it more girlish, but I think you could make some other changes before making that decision. If you have it in your budget to buy fabric, I would cover your beds in a solid color fabric to make the quilts pop more. Try hobby lobby for some cute wall decor. Last year, I found an adorable glittery wood wall letters that said "kisses" in the valentines section. It goes perfectly in my 5 year olds room. I would hang something like that above each of their beds. The dresser needs something cute on it. A little grouping of bears, blocks, picture frames or just something more decorative. You could paint some butterflies on one wall with just a few small pints of sample paint. You can get these at Sherwin Williams for $5 each in their cans designed to help you decide on a color and you can mix them in any of their colors. It would add a lot of pizzazz to the room, and a butterfly shape is pretty simple shapes put together. I would then add some cute basic curtains, maybe in a solid color. Good Luck, I'm sure they already love it, we always overanalyze these rooms, and I am sure they love it just the same now as they would later.

Queen beds are 60x80 inches . Do the Math. Technically speaking, they "will fit". There will be very little room to move about the room and no other furniture would fit in the room. Seriously, unless you're running a brothel, why would you do this? If you had to, then consider https://m.colemanfurniture.com/lake-house-stone-full-loft-bed-with-full-lower-bed.htm?gclid=Cj0KCQjwm6HaBRCbARIsAFDNK-jYlciAmgQCi8aSCTPPfjKnCmi_Rr_Qt5aRr9v7WxHCXn8POCKFSHQaAh3dEALw_wcB

As to furniture placement, create zones -- one part for sleeping and dressing and the other part for your school work and leisure activities. Red for a wall can be a difficult idea to sell to homeowners. So is purple. You might promise to repaint the red accent wall white or another color just before the house is put up for sale. Red might also be a selling point if you're working toward a theme that makes red important enough for it to be a wall rather than just red accessories -- for instance a red/white/blue patriotic theme. Luckily for you there are a lot of different shades of blue -- very light to very dark. You could choose blue denim -- new dark blue or lighter old faded - or a bold cobalt blue. Before deciding, consider an overall theme for your room. Would you want flower garden or beach or mountains or patriotic or something else. That can help you choose the shade of blue. Also, you can still add red on your wall another way. Fabric: You could hang a red rug or red bedding such as a quilt or comforter from eye hooks attached to the very top of the wall next to the ceiling where there will be a top wall plate of wood boards to hold the weight. Wood: Is anyone in your household DIY inclined? Does anyone in your home shop thrift stores where you might find shelving (such as Habitat for Humanity Restore Stores) at a budget price? Any shelving you can paint your favorite red and hang on the wall has the potential to make the wall predominantly red. https://www.pinterest.com/pin/377528381246213109/ https://www.pinterest.com/pin/338262622014252931/ https://www.1stdibs.com/furniture/storage-case-pieces/bookcases/set-of-three-wall-mounted-bookcases-hvidt-mlgaard/id-f_13146401/ If you pull your bed away from the wall, you might even consider floor to ceiling shelving -- red, of course -- against the wall behind it.
