Hmm, lotsa photographers with their big cameras so I was a bit reluctant to wait in front of the shop in the beginning. Size does matter in this case...
The catch is the models are standing behind the mirrors, so if you use flash, you are actually ruining the shot cause of the reflection. See, there are a lot of people there.
This is what happen when you are taking a picture while running to the other side.
My shot is a bit to the left because there are too many people in the middle.
