Thanks Phil!
All advice is certainly welcome.
After reading these threads that I should try to create more of a 'brand' that I can also put on the card.
So now I am in the process getting a logo designed for 'Australian Nature Photography' to try and create an easy to recognise 'brand' that I can also add to the business card.
I will post back when I get a logo and will see if I can add it to the designs suggested :-)
