I'll post my results later on, I've got to go to a restaurant for something with my gf...lol
EDIT: WOW! Great job man. It's compicated and you loose hope at first, but if you keep going, there's one layer, I think its the 1st gradient mapping layer, that just makes the sig 100 times better than what it originally looked like. Tips: If you want people as lazy as me, but with less experience on tuts, say some time between the begining and the 1st gradient mapping layer that it looks bad, but it will get better. It's really confusing too, but it's worth it. I have my best sig so far with this. My only good Daniele De Rossi sig too.
Also, if you make the last render the way A.C Milan's render tut shows you how to, and then do the gradient mapping thing, it looks even better.
Here's my result:
