Seems that you might go and find some digital images - very casual , of she and her friends not paying attention to the camera. A big group would be best. Take it to kinko's and see if they can print it in sepia tones in a really large size - see how big they can get it until it is pixelated (don't go so large you lose image quality)- something like 30" x 40" would be super. the sepia tone will make it very special and fit right into your color plan.

Before you do that, get a super large frame - look at the local thrift store for any huge frame with glass (disregard what is inside). Cover the thrift store frame with silver leaf paint from michaels, and then take your image and the thrift store frame to michaels. Ask them to cut a chocolate tone mat between the photo size and the frame size and to put your image into your frame and glass - the charge for a custom cut mat isn't the big$. They will set it up for you - hang that over her bed so she has one big art thing in her room.

Can't see the rest - not sure the multiples are better - I know how this happens when you get excited, but I recommend an edit. Keep the one fluffy rug by the bed and take back the bamboo mats. Three terrific frames, all silver, take the rest back - it is too much clutter by the time she starts using the space - she needs a clear counter to start. She already has a few things that need to stay, so let them breathe.

You might hang the new mirror on the wall above the dresser- however tall she is - figure her eye level when standing is the middle of the mirror. That will give it a cleaner appearance - with the 3m command stuff, you can hang anything and not mar walls.
