The back looks good. On the front, maybe try something different with the text? It looks a little standard\plain the way it currently is. I like the colors but the layout is a little boxy and standard. I like some of the other designs that have some curves and such. Thanks for all the entries thus far!
Hi jd-- I saw the layout on your website; I was just trying to match it so that people who view your website can remember that they have your business card; you know, brand recognition. But if you don't like it, I'll do another revision. Thanks for the feedback!
