Am playing Majora's Mask for the first time with the 3DS version and its quite marvelous. I'm glad I can truly appreciate your work since I have played it.
You should totally do the others(though I have just gotten the Goron mask).
I like the "kid-like" look to it. Is that a style you always do, or did you do that because the Deku Shrub looks like a little child? If not, it'd be cool to have say, the Goron Link (if you decide to do it) be a different art style since he's more brutish, etc.
