I hate people waring sunglasses in photo's. It's my contention that the eyes should be visable, they are as they say"windows to the soul". No eyes visable means its difficult to relate to the person in the photo.
I quite like this, I presume the interesting side effects are due to the camera?
As for sunnies, well most people do wear them and I would say her facial features would really be screwed up if she took them off for a shot. As it is, it's a great picture, touristy, but great!
