I agree with that plus: the Federer service really really nice!! but you got the service waiting animation false, it is indeed really bad: try to make him lean more like that:
yea, i dont really like how he starts the serve either, but the rest is good. i think it should be a bit faster and the ball should be thrown in the air a bit more too. also, the second backhand in the game which is supposed to be Fed's , doesnt really look like his BH either! when Fed uses his backhand his body stands still, and his right arm moves toward the right side, while in the game, his arm moves along with his body towards right! not really federer like.
