I see on your Profile this is your first movie on newground.
Its pretty well done for a first try. Have you made other stuff like this before? If you did you should put them here / Give us link. :)
I love Shovel Knight, I'm looking forward to watch your serie.
Best of Luck.
Btw; I don't think voice acting would make this better. You nailed it the way you did. It keep it true to the game imo.
