I like this look! Pixie punk rock chick kinda works, but I do think Miley looks better brunette. If I were her I'd let this grow out, dye it dark brown, & try again.
I like her with shoulder length hair but it'd be interesting to see her in long dark hair. She has such a pretty face, i think bangs n a dark bob would be a good look.
BTW, her MC cover is Gorgeous! Might just be the BEST cover shot of the year!
