First of all i think running through a basic tutorials.
I can see that youv'e tried brushing a nice background, but the sharpness of the blue colour doesn't make it too visible.
Its positioned ok , but is overblended a lot.
Reasonable size, But hard to read.
I think that you shouldnt use bevel and emboss over your signature it self. Take more time when coloring the sig, (Soft light / overlay are useful). Add your render once you like the feel of your background. Position the render where you want most attention to be (Focal). Then just blend parts into the background. Keeping the Focal point nice and clear. Once your at this stage you will notice your sig is coming on nicely, and therefor you can add some nice text and a simple border.
Didnt want to go in too much detail yet as i think if you run through the basics first you will gain more skill.
Thanks + Keep us posted.
