A square deals with a triangles mess
Positives: Good layout and fun characters. Sync dialogue is impressive. Interesting and effective images used to describe the square's accusations of the triangle.
Improvements: Give the triangle more expressions. I.E. when he steals the cupcake he could smile or have some expression on his face that describes his thoughts before he eats. Go to a closeup of the triangle to show its expression before it vomits.
Positives: Made me smile. Nice punchline. Characters emoted nicely.
Improvements: With as simple as the characters are, I would expect much more fluid animation. The vomit would have worked better off screen, using sound alone would have been more effective and funny.
Positives: Excellent writing on the animation. Pleasant simplified characters. Wonderful explanation of how and why the prank occurred. You need to keep writing. This is great stuff.
Improvements: The movement in the throwing up could have been shown, staying completely still doesn't work.
