Very fun, but not perfect
Very enjoyable. The best part was the cockney's rant, which was near par with a good Monty Python skit.
That said, you need to work on pacing.
Example 1: The song the geek was singing at the begining was so painful I nearly stop watching (glad I did keep watching, though). It adds absolutely nothing to the cartoon and perhaps is the least entertaining moment in it.
Example 2: Too much dead space. By that I mean moments where the action in the particular shot has already taken place (or the character has finished talking), you stay on the shot for several seconds before cutting. An example would be how long it takes to cut after the cockney's rant; wouldn't it be more effective if the audio is timed to finish as he disapears off screen?
But really good job on this. I laughed aloud.
