What to get for Christmas? (8th grade girl)?

I'm in 8th grade and a girl, and i know its a little early to be asking about Christmas already but my parents are already asking what i want.
The problem is, I don't really know what to request. I already have many luxuries, including an iPhone, iPad, Macbook Air, Xbox, Wii, a good camera, clothes, PLENTY of nail polish, etc.
I know I probably sound like a complete brat who gets whatever she wants, but my parents just insist on getting what I want (i'm pretty lucky for that) Also, i have good grades, and attend one of the best schools in the country so my parents are pretty proud so they're willing to buy me things.

Since I already have so much, I've considered simply requesting money or gift cards rather than real gifts.
However, some of my talents include music, (I play clarinet in the top school band) and i absolutely ADORE art. I've also considered asking for the Prismacolor color pencil 150 pack,( i already have the 72 one)

But, that's All I CAN THINK OF, and my parents say i should ask for more, or else they are going to get something i won't like. If you guys have any suggestions on what to request for Christmas, I would really appreciate it!

BTW: I'm not really girly, and I'm not allowed to wear makeup so… Yeah.
Please don't leave any comments on how spoiled i'm, (i already know how lucky i'm, and am so grateful for it.

Ask for art supplies you may want or a gift card to an art store! Colored pencils and sketch books or drawing books are great ideas.
You could pick a charity of your choice and ask for some money to be donated in your name. Whether it's a local animal shelter or a foundation like WWF! You can donate whatever amount you want and it's a great thing to do.
You could ask for clothes or gift cards to your favorite clothing store.
Gift cards to a music store or some sheet music or music books for the clarinet.
iTunes gift cards, xbox games or wii games you're interested in.
Hope I helped!

When I saw x-mas presents for a 8th grade girl I thought I would throw out concert tickets for an easy 10 points. However, upon hearing of all your good fortune and the tone of your request I think you have the answer already. It seems as if you have a good enough grasp on your life's good fortune that the answer I propose shall be the most fitting and truly rewarding.

Pay-It-Forward.

Explain to your parents how blessed you feel and that you would like others to feel blessed too. Ask them to donate whatever gifts or money they would spend on you to those less fortunate. Not only is that a gift to those you'll help, but for your parents and yourself as well.
