Classic cartoon gags never get old, and getting them right is all about timing, pacing, and conveying expression.

In my sincere opinion, you did great on all three! Quick, short, sweet, but most importantly, it's very easy to tell what expressions and emotional states your character is making. I rewatched the animation with the sound muted, just to see if it'd work even without the added voices, and quite honestly, it does work.

If I had to go digging for a nitpick, it's perhaps that a -little- too much time is spent on frustration and on gloating, but since this animation is self-contained and not part of a larger work or episode, I'm giving it a pass; you want to show off what you can do, and for lack of better words: you got it!

Hope we'll see more from you soon, you've got something good going on here.
