Metallic, there it is, I used Trajan Pro for the font, very elegant and the colors of mexico. You talked about a "sensation of freedom" the sphere that is floating and not attached in any way represents the freedom. Also happiness is represented by the flashy tone and color variations, bright red and green, still keeping the real Mexican colors intact through the milder tones. And last but not least, a 3D effect, and shadow. All this done in vector.
I hope you like this.
Thank you.
