Your features are so striking and edgy.. You are insanely gorgeous! I love this look, the photos are a little dark but you look great, very model-esque.
I think your brows look good the way they are, but if you decide to go lighter I think they'd look good maybe just a shade or two lighter as well, I'm sure you would pull it off!
And I have to add.. I'm definately in love with your hair, it's gorgeous! I would do anything to have hair that color.
