Heres an honest review...
Lemme break this down into sections..
Grapics - You took the Super Flash Bros tutorial a bit too seriously. The models look the exact same as the green dude except coloured. Take away the lines on the joints to make it look more natural.
The lip syncing is horrid. The point of the 6 mouth system isn't to let them loop while someone is talking. It is to use the appropriate mouth for each sound.
Style - Though this is a somwhat original idea, you stole it from that little sub-cartoon on Garfield. I saw that skit when I was 6. Stealing jokes isn't cool... Refrencing them is fine, but stealing them isnt funny...
Sound - Very good voice acting! The sound level was fine for me so I have no complaints.
Violence - No violence, no comment. Very simple.
Interactivity - That car was so simple yet so fun. I love it!
Humor - Same reason as style...
Overall it was worth watching and you have potential to be a great flash artist. With a little work you'll be great! ^_^
