This is really strong... it has a rather timeless feel to it, which goes against the very nature of most fashion photography, which is almost inevitably vogueish and up with the 'now'. The sense of movement is very successful, I think... it gives a real sense of personality and 'aliveness' to the model.
One has the impression in this successful portrait that it influences erotic the spectator, whereby it could endure something else more at sharpness. Sincerely Gerhard
