I saw this picture before ( on Tumblr ). I even have it in bigger version:

I also thought that it's Miranda but I am not sure for 100% because Miranda has wider nose (plus a small hump), longer eyebrows and healthier skin. I've never heard about this photographer. This girl has a little mole on her right hand - Miranda doesn't have.

Yeah, not to mention her eyes have never been that vibrant. Hard to tell though
