What Do You Guys Think of Hairstyles/cuts Like These on Girls? Please Answer!?

ok so i'd always had really long and super thick hair growing up, but for the past 2 years it's been about chin level. now i can't decide if i want to grow it back out or cut it way short lol. i really like it short, but every now and again i miss being able to pull it up in a pony tail. anyways, i'm 21, almost 5'9, average size and my face shape is kinda oval shaped, like the picture of pink in the first link. also, i'm pretty pale, with kinda big blue eyes with light blonde hair. i've never dyed my hair before, but i'm thinking of dyeing it a medium brown and cutting it. what do you guys think? also, what specifically do guys think of girls with short hair? like it or not? why? thanks

Suggestion:

I'd go for it have you seen Emma Watson her cut looks amazing on her.If anything you could always buy a wig if you're up to it for those days when you want a change.
