That's an awesome cover, I love how it looks like leather work. The smokey eyes are really hot - and I think it's the eye make up that creates the illusion of her looking pissed off. I'd describe it as a more serious/contemplative one, it's as if she's looking at you and judging you, are you a hero, or a thief? lol I'm taking it too far, but yeah.
And I hope to see this 1800's theme she's kinda got going on in her next music video. It'd be hot to see her all Victorian Era'd out.
