OMG this cropped version would have been an even BETTER cover.
I think it would have been perfect if only not her "dirty" hair closest to her head was shown. So it could have been cropped like in this but shown the mouth and that white feather thing aswell.
I really don't want to bring other pop artists into this but the distinction is being made here.
Britney is going for a non-gimmick type look -- simplicity. Contrasted to other artists like Lady GaGa's over the top dramatics, or Ke$ha's trashy persona.
