Which Is better on me? (long question ) (face shape...pics...etc..)?

I think you look the best in 4. To be honest though, I would change it up a little. It almost all looked the same. Guys usually don't notice subtle differences(at least I don't). I would try blond or something, freak people out. Guys that didn't like you before might like you all of the sudden. You'd be surprised. One day dark straight, the next day skirt, blond and pigtails lol. Or maybe at least go a lighter brown and make it wavy or something. Just my opinions. You'd look good no matter what tho! Good luck!
