Nice court, there's a couple of things I think could be improved:
creating a shape the size of the court and filling it in a single colour means you lose the detail on the court - e.g. where players have slid on it to make marks. I think these make it look more realistic!
once you have tested the court in game (and if you have photoshop), use the content-aware fill tool to add a little more dark green to the bottom left corner, so it goes right up to the line
you can also see the shadow of the umpire's chair abruptly end - this can be really tricky to avoid if the net is wide, but try and just erase the bits of the net that don't have shadow behind them if that makes sense!
