good movie, tho try making mario to be in talking animation when the voice starts, because from the part 1:07 to the 1:17, mario was not talking at all,(the voice was heard, and it was ok, but the sprite of mario stood still, in the punching tree pose, instead of being ina talking pose/opening mouth) and he was just stuck in the ''punch a tree'' pose for a long time.(instead of opening/closing his mouth to luigi, or at least to be standing in a different pose)
so, add more poses, add more story into this too,
(because honestly, if this is the same story of bowser VS mario, this will not get any awards for originality, and you should be original, if anything)
so add different characters, enemies, and or more (or DIFFERENT) elements in your story, and make this an original mario story at least.
also, if you could add some humour in this as well, it coudl be nice. luigi is always great for that.
anyway, that is all, other than those things that i pointed out to you, your part was good.
keep it up. you are p. good.
