Layers are always an effective way to change up your style. If you are not a fan of bangs, I would gofer shorter layers around the face. Starting them right about lip length and connecting all the way down to the ends would really help to create more body and style surrounding the face. You can also add layers through the length beginning about the back of the neck and gradually getting longer foam there down to the ends. This will really help to revamp your current 'do and give off a new style feel.
Do you just want a different style? I mean, instead of straight and loose? There are tons of different styles you can do: braids, buns, ponytails, etc. But, if you're wanting difference in color, some highlights would look great on you.
I think you would look great with side bangs....Bring the length up and angle the bangs into the sides. I think your current style is elongating your face. Add some texture/volume to the sides. The photo attached would be a cute cut on you!
