ROFL
at first i was just sitting there... omg this is gona get blammed, but then i thought, hmm nice start up. Then the music was kind of annoying becuase i thought that you were going to totally make it crappy. it was kind of slow but when he started running... BOOM! tripped, i laughed my ass off! i rarely get that kind of laugh, very nice, i voted 5 becuase of the perfect timing of that fall. i was laughing like, omg is he gona get up!? very nice. Now on how to improve.
Smoother Animation: When he turned you could have added 1-3 more parts so it looked like he actually turned around. The running was pretty good, the character design could have EASILY been better, so next time work for about a day looking for designs and thinking about it. Decide what would be best that you could still animate well.
Music was kind of quiet, i could hear it but it sounded like a bad microphone recording. could have been a bit longer also, maybe added 2 more ways that would make us laugh.
