Medium, curls or all the way?

I've had all kinds of hairdos and colors. Short, page, bangs, long. Red, dark, blond. But for the first time I've been patient enough to get my own hair-color - medium blond. But now I'm considering trying something else. Not something dramatic, but I'm thinking about getting either curls or a more blond hair. What do you think of these hairstyles - should I get one of them?

1. Highlights

2. Very blond

3. Curls

4. Curls with bangs
