I find it funny that the doll had more detail than the child playing with it.
Since this was made last year I have no clue how much you have improved so I'll just say keep things consistent. I saw what looked to be earth and then the bottom of it exploded. "Oh, Antarctica exploded." I thought to myself as that is where the explosion happened on the drawing of the planet. Nope! It was Alaska. The story was shaky as I didn't understand what was going on. Why did the sister have a weird green potion? Why did the brother want it? The humor was ok and all in all it was an OK animation.
