kaikai

This is the design for my new business card. When putting in my last name for the second Kai the name is longer and looks a little better. Two questions

1.)Should I put the name in black? or keep it white?
2.)Should I put my email address on the card for contact information or just my website with my email on it will be fine?

Your opinions on it will be appreciated even if you have more opinions beyond the two questions.

Thanx
