Some "Quickie" Logo Designs

Wanting to create something very simple for a business card assessment we are doing in InDesign.  So here are a couple. 

I tossing up between pink and black as the background colour on the business card.  Let me know what you think.  Which design do you like?  If you check out an earlier blog entry you will see my first versions of the logo with the black.  Logo Fun. Opinions welcomed!
