Very well done by the model. Very well done indeed. The photo is way too noisy probably from the long exposure and slightly overexposure. Even with that it is a nice photo
The head is a little lower on the left than the right - not symmetric and does not meet challenge.

Good set up and idea for symmetry. Did you try a longer exposure to get more definition of the face in the two positions? That might be a little stronger. Good job.
This is a very interesting photo - I love it. I assume it was taken using a long exposure and double flash. The detail is lovely and the graininess is wonderful - especially in the jacket and denim. Well done.
