I'll think about making some new football/soccer players. I could draw more Real Madrid players (I'm supporter of this team) or perhaps some of the best players in Europe like Iniesta, Drogba, Maicon or Rooney 
And yes, I agree with your opinion about today balls, it's like Pikachu can come out from inside the ball! xDDDD
I KNOW modern soccerballs can look like that, but I immediatly thought pokéball anyway! 
But pic looks great. The round patch of grass make it seem like some kind of collectable. Make some more so we can get the entire set
good, i like it
