Metro Espresso "Business Card" Design

During the week, I designed a "business card" for the Metro Espresso blog.  Something simple, something to the point, something easy to print.  I like it for conveying the most important information, the url and that ME is a coffee blog targeted towards DC.  Additionally, it has the DC flag design on the cup.

Question:  How would you improve upon this design?  Would you add color? Email?  Twitter user Cagrimmet recommended adding the saucer and rounding the cup.  I added the saucer, but I need some more work with rounding the cup.  My GIMP skills are the equivalent of a toddler. 

Also, feel free to design a Metro Espresso business card yourself if you have the free time!  I would love to see user creations.
