Manutoo ,it will be really cool to have some other features in the clothes such as:
1)Having different hairstyles(including baldness for players like Ljubicic and Davydenko
)
2)To have sleeveless shirts like Nadal and Del Potro
3) May be 3/4th shorts like Nadal,s and the current headband is a bit wide when u look from the front.It covers all the hair so it looks like the player is wearing a cap.You have to swing the player around to see whether he is wearing a headband or a cap.So u can makea some hair come out of the band from above to make it look more cooler.
