An absolutely GREAT idea for this challenge, and I think you've pulled it off brilliantly. The court lines and colors are sharp and bright, and the ball has just the right amount of blur to suggest that it's an actual freeze-frame from the US Open where Agassi got a bad call (or whatever). My biggest complaint is that you thought of this and not me. Bravo and kudos. I hope you score highly with this.
Like it, great contrast between the court, the line and the 'out of bounds'. I will give you an 8, would have been a 9 if the ball was bouncing and compressed.
