Hello I'm new here and this is my first tag that I have ever created...don't be too harse.. ^^... CnC please..
For a first sig its fair. What i notice though is, the render its self is faded way to much into the background you can hardly see it. You render should be the object that sticks out most. You might wanna add some more brushes or other objects in the background. It is kind of plain. Last dont have the text right on top of your render either. U need to add something on the sides of the sig. But for a first one its ok keep working!
