Some graphical suggestions for the next versions

Next versions of FC suggestions :  1 -The ball could get dirty and grassy effect by touching shoes of players and also gets effect of snow and rain on it and also players get that about snow and rain and dirty and grassy shoes   2 - All fans monitoring the balls exactly because in highlights when  I checked they don't look angels of the field when the ball or the goal scorer move on . 3 - When the match finishes the population of fans in stadium could change . 4- In ceremony of final cup during celebration of players confetti papers should stay on the field and don't hide them  5 - When the referee uses his/her yellow or red card from front view the referee puts the card in his/her pocket exactly and don't hide the card please .  6- Showing scars sometimes after intense fouls or injuries on the place of hit players 

I hope these help

Thank you
