I like it but I think it's quite dull and there are a few too many stars. Other than that, it's sweet.
If you want me to be honest, I don't think this is your best work. You need more colors. Something that says, "You looking at this? Well, if you get me to do your graphics, people will look at yours, too!"
Doing circle logos are overdone. Too many stars. And I feel the 'G' is too thin. More colours would be nice as well.
