Ha! Funny ending.
Alright, well, the first thing I notice that really could use some improvement on was the person's hand as he was reaching for the $100 bill. It kinda looked like a seagull's claw minus the talons. The walking animation could use some work as well, considering that he looked like he was sliding rather than walking. Unless this is your kind of art style, the head was disproportioned from the rest of the body making it huge and freakish. Lastly, the city scene needs more life! Add some pedestrians, magazine stands, hot dog carts, and homeless bums! Good luck next time when you create another flash!
