I have no idea...
...what I just watched, lmao. I found myself laughing aloud. It was odd, but cute. But, I do have some comments.
The walk cycles bugged me. They were too stiff for all of the characters. The legs should be bending where the joints are and also, they should be bobbing when they walk.
In terms of lip syncing, their faces should be animated accordingly when they go to open and close their mouths, not just the mouths. Now, I don't know how to go about animating a jawbone into a peach and a pineapple myself, but there needs to be some indication of movement in the characters' facial structures. Mouths also aren't ovals.
Make sure to put anticipation into the motion of the ball.
Lastly, work on perspective. There are problems with the bookshelf and the rug as well but the couch has the most issues.
That was suprisingly fun
The voice acting could use some work as it lacked effort in my opinion, it was repetative and i found the constant Ooooohs slightly annoying. The animation was quite good probably better than anything i could do. To improve i would work on the plots of your animation more and try a little harder with the voice acting.
This was quite funny, loved the voices!
