Pretty good, the background art is beautiful, the chirping and wind sounds were more fitting over adding music whatsoever, and the added bee and leaf plant detail for the ball throw response was nice, along with the trees and grass reaction as well.
My only criticism is that where the second shot of the man throwing the ball (00:16) only the ball was colored except for the man. I would have given this at least a 3 1/2 out of five but since it sounds like you had this idea yesterday and took one day to work on this, I'd give this a 3 out of 5 for posting this as soon as possible. I think taking a little more time to color in the second ball throw scene would have made this a little better.
Edit: I saw your updated response and watched it again, and it is definitely better and more finished than before! Instead of 3 1/2, I'm giving this 5 outta 5! One for motivation for the finishing touch and another for taking in criticism as an opportunity of improvement!
