Greatest advice that I ever got from a professional photographer ( Joe McNally) is that it has to catch the eye from across the room and someone accross the room should be able to identify exactly who that is by the look of the card and not by what is printed on it.
I to am a sucker for all black cards with minimal writing on it.
Most people will just type your name into the address bar for your website so I don't think that the website portion on the back needs to be there.
The front is very nice, simple and elegant.
The back needs some work.
What type of photography do you do? Black represents high fashion, high priced style photography and people will be turned off immediately if they sense a high price.
Did you have any other ideas drawn up?
This is all constructive criticism.
