Unfortuneatly, I am not a print guy and came up against the same problem when I was looking to create business cards lol. However I would personally go for adding a little more design to the background being a designers business card. Alternatively a picture of yourself seems to work well.
My only other comment would be to give the business a little more alignment as it currently looks a little all over the place and nothing flows quite right. Perhaps left align the logo / your name etc and right align the contact details?
Just an idea and only trying to help. Someone in the print area may be able to comment a little better on this?
