Wow, this is one of the best work i've seen in this website.
Truly incredible.
The only one problem i see is its aplication in a red background (like in Austria's home shirt), because if you turn the badge white, the center (where the ball is) looks kind of weird... i mean, it doesnt look bad but it looses some of its strength comparing it to the red logo/white background you show here.
Congratulations, this is one of my favorites :-)

@JCPierola thank you very much, I am really honored by your words.
actually when I published the work I have arisen doubts.
I should have used more than one color. that's for sure.
thanks again.
