I think you should make his racquet go up in the air a bit faster, and make him throw the ball up in the air higher so it can look like this:
That's a little bit problematic...if I speed up the things, the ball will actually be lower in the air...to determine the height of the ball and the trajectory, Manutoo created a sort of algorithm that take in the consideration the frame where the ball is being tossed and the moment when is being hit. Being an algorithm, i can't always match each player's hitting point..some player are hitting the ball when it's in a downfall, some player when it has reached the maximum height and some when the ball is rising up in the air.
I tried to match exactly Federer's ball height but the animation looked overall a little bit slow, like he was serving in slow motion

You're right here..I tried to make it last longer but I had some serious smoothness issues.
Anyway, as I said, take a look at Federer's serves hit on the left side of the court...you'll notice that my animations and the real one isn't that different as you think it is.
Indeed, the way it raises the right hand in my animation is a little bit larger than real life but not so much.
Today, I made some small modifications and it looks better...I'm trying also to make it last a little bit longer before hitting the ball; the issue, as I said, is to make it look smooth, not to just make it (which is easy)
Im glad i kinda helped you in a way by telling you whats wrong!
