I don't really know what to expect from this. is it funny? is it serious?
the premise seems funny, but the trailer here didn't really show that off.
as far as future trailers go, you might wanna throw a bit of humor into it, rather than making something serious/actiony.
of course if it IS a serious toon, then I'd have to question why the main charector's a milkman who was bit by a cow, lol.
just keep practicing, and try to keep your theme strong
also the music was a bit ill-suited
