Oh, I like this, it's cute and simple. I don't agree that it needs anything in the background, honestly, but I've always been a fan of very simple colors and minimal effects (ie my icon). However if you do want to add a subtle pattern in the background, there is subtlepatterns.com for that.
As for the type itself, maybe try making the shine a little higher and a tiny bit brighter? What you have isn't bad, to be quite honest, but it does feel like it's missing something.
