I like, even if you copied tutorial. I would have been better if you used a shade of brown, maybe even a small drop shadow to make it more pronounced. De-saturating or adding a gradient map for the space stock may have helped to blend it in.
I like use Default Fonts, like Times New Roman, looks sexy and works good in a signature!
this sign looks awesome but the real thing its you give 2 light spots that doens't exists.
The light come from the top, and you make the focus dessapear with those effects;
