Okay, I dont wanna give you too much advice because at your age, you shouldnt worry about looks that much. NEVER WEAR FOUNDATION AT SUCH A YOUNG AGE!!! Just saying, it makes you look either fake or old and you dont want that. Eyeliner only on te upper lid would make your eyes POP! And mascara, and if you want to be daring and use eyeshadow go for matte colours ((light brown, peach, etc)) just on the crease of your eyelid. Straighten your hair or do loose curls like Miley Cyrus. Dont wear too dreary colours, just wear yellows, greens, blue, mostly things you can find at Old Navy or something. It also depends on what type of beauty you like like, surfer, or goth, or anything. I hope I helped.
