Help me create a new style for myself? :)?

I've decided to mix up my style a bit as im just sick of looking like everyone else. i dress casually normally jeans and a tee, and kinda bored with it! i want something different and need help doing that! i take inspiration from many different people, pixie lott, cheryl cole, demi lovato and miley cyrus. thought they have quite different styles, i kinda want to blend different aspects of theres to make my own. :) any ideas of my key elements or shops i can work with?
