Hey Christina, thanks a lot for your work! I think the overall spacing is working. The main things I would recommend is to watch your timing and your curves when the ball hits the ground. There should be a sharp angle on the bottom and a nice arc on the top. Right now I think you have nice arcs on the top but the timing distracts from the trajectory. It feels to me that the ball keeps the same speed throughout and it should come down faster and come up slower. I think it would be better to talk about it in dailies so I can better explain myself.
