Should I Go from Bob to Audrey Tautou Pixie?

So when my hair was long like


I never really did anything new with it. But now that it's short, every few months I feel like I need a new style! Here are the last couple of iterations:










And now I'm sort of wanting to cut it pixie short, like Audrey Tautou.












I was (and still sort of am) unsure whether I could pull it off/it's a good idea, but a few coworkers said I should try a pixie. And then a few people said it was a good idea, if I kept longer bangs (and others said the bob is so good).

Is this a good idea? Do you have any other pixies/longer haircuts I should look at? Should I trim it back up so it looks like my last cut (it's been a few months)? I do love my bob, but I also think a pixie might be pretty exhilarating!

So: pixie? bob?
