hair cut?!

So ive been thinking alot recently about cutting my hair super short, Its at my shoulders right now...Im just trying to look at lots of pictures and styles to see if thats what i want to do or not...
Something like this...


Really i wanted a Frankie Sandford (UK girl group singer) type hair cut, but hers is a bit more dramatic than the one above, so im think of getting the top one, like Victoria Beckham and then if i like that and am comfortable ill get the more dramatic Frankie cut, which is this one below.
