Preteen Bedroom/Guest Room

I recently had a client that wanted to move her 11 year old daughter into a new bedroom that would also be serving as a guest room. She already had bedding that she loved, but wanted to upgrade the design and decorations to something that would work as her daughter gets older and also for guests. Here is the before picture:

This is the design that I created:

I would put the white chair in the nook with the cute mirror behind it. I would put the peachy/salmon rug under the bed with a natural wood nightstand and a creamy white fabric headboard. I would do white knotted curtains to frame the window and cute fairy lights on the wall opposite of the window. I know that you were going to use her room as a guestroom as well, but it is always fun for girls to have cute fairy lights in their room! It would also be cute to do a gallery wall with natural wood frames above the bed with artwork that matches the colors of the room or your daughters favorite photos. It would also be fun to add a sparkly chandelier or a flush mount above the chair in the nook as well. I would do white sheets under the floral bedding and blue throw pillows and a blue throw blanket to bring out the blues. When you make the bed, fold the comforter down so you can see the white sheets. And of course add some greenery either in the corner by the window or on a nightstand by the bed.
