I'm sure if you sharpen that pencil thin enough you can do a decent copy of her style...I just fear it might smudge more than the liquid liner...I personally never tried her style, I'm not one for symmetry on my own face, haha! But I don't see why alternatives wouldn't work. And the choice regarding your hair...I guess that depends on the length. If it's almost the same cut, it'd be cool to spray it silver like she tried herself...But that's all down to personal preference, just do what you'll have most fun doing!
