try Benjamin Moore Key Ivory West for the walls - it's a soft color and will brighten the space, but will work with other colors. Put a funky rug on the floor. Go to Marshalls or TJ Maxx or IKEA and get a comfy chair with a a small table next to it. If she has any artist friends at school, have her ask them to do an oil or watercolor of something she likes in a large canvas for over the bed (don't frame it). Replace those lights. Or, for over the bed, just print out a bunch of 5x7 photos of friends or whatever (black and white would make a statement) and arrange them in whatever frames you like. Going for neutral or soft colors will enable you to use accessories for color and change the look when it gets old.

It's refreshing to see nautical, navy BLUE. Everyone is saying the same thing for the most part - just introduce another color, definitely bright (yellow or orange IMO) and it will make it more current. What I really like is how your style will withstand the test of time - and with minor updates now and then it will always look fresh and "current".

go to www.etsy.com and check out HAND made items by artists and crafts people. You never know what you will find and it is very, very fun to look and learn about the incredible things people fabricate. One nice item that comes to mind that I have seen on Etsy are "Beach blankets". I did not know about them because, I've never lived by water or the beach but, apparently if you live by water you always want a big, light weight fabric to use to sit on or to stretch on poles to shield you from too, much sun. I f there was a big "beach blanker" that you liked enough, it could be in your room as an extra blanket, throw or as a window covering perhaps. This would be a good way to remind yourself about your love of the water and surfing and the beach. https://www.etsy.com/shop/AMIZANTI?section_id=6832219&ref=shopsection_leftnav_3. Maybe this is kind of an exotic option for you at your age but, I think its never too, soon to attune ourselves to culture and the arts and interesting ideas from across the world. Also, on Etsy (not bedding) are wall murals. My client's son Max wanted to feel part of the woods so, I found and he and his dad installed an incredible mural. So, that might be fun for you to explore too. I am showing the one they picked here. We did not stick to any kind of bedding collection. Instead we bought a big combination of Max's favorite "Forest Colors". See bed picture for example. Think outside the box, have fun!

Buy the bedding you love and then go from there to doing the rest of the space, paint is cheap so leave it till the end of the process and match to something in the bedding would be my suggestion.
