I actually DID completely miss this, until just now! Nice effort--I do agree about the soccer goal distraction, and of course, those flames. I like the idea of at least showing the kid one without the flames--even if they don't agree it's better without, you will have exposed them to the idea of "good taste," and maybe in future years it will take hold. LOL.
I actually LIKE the size of the number, though. Maybe not everyone does, but I had a certain pride in my jersey number when I played sports, and would have wanted it to be just as prominent as my name on something like this.
