How do you become a fashion photographer?
Looking at your flickr stream, I see no people at all, so am interested in the leap to fashion, one of the most competitive areas of photography.
If it is a real interest, I would suggest you start photographing people young and old, master the art of portraiture. develop your own style and read and look at fashion magazines. Dazed and Confused through to Vogue. There are some groups on flickr who will critique fashion shots, it might be worth looking at them.
Good luck.
