Improvement? huh?
I honestly liked it better when I couldn't tell what they were saying. The audio file is now comprehensible, so that I can make out the lyrics, which consist of rhymes such as "super mario RPG, It is a game that's for you and me" and "there are many secrets in this land, up in the sky or beneath the sand"... people seriously are impressed with this? It's like when a third grader is told to write a poem for english class.
I don't understand the other comments saying that your animation skill has improved. The animation here, to me, is as painful to watch as in your previous work. Mario's 'run cycle' consisted of him flailing his arms and legs around awkwardly, his fists becoming GIGANTIC at certain frames, at a choppy framerate. I would say 'you can do better' like many other artists have suggested in their comments, but after so many years I'm not so sure anymore.
And who honestly ever had this much trouble with that forest puzzle? It's not THAT hard to figure it out.
