get a nice hairstyle

I hate my hairstyle i want a new one lol! i know its not hard but im scared if i get it done it wont look right and ill look a complete geek lol i want to have my hair on a slight side parting with a wispy fringe with a few layers and different colours like chocolate browns, blondes and maybe a few reds. If any one thinks that it will look okay on me tell me or if you have better ideas plese feel free to share them with me! xx
