Awwww....
You took away all the scariness and edge in his persona and made him sorta cute. I can respect your artistic license there, but I think the contrast with 'Winter Wonderland' woulda made it worth keeping (i.e., when Christopher Walken smiles, he looks like a hyena about to eat something, in reality).
Anyway, it was a decent joke, and the animation was the work of a professional. The Walken impression.... well it definitely woulda been clear who you were doing even without the animation, and you weren't afraid to really get into it with the tone and diction, so I think you deserve props for that.
Finally, you ended it early, mercifully. Because as much as I love Walken and Walken-related parodies, that was enough. Nice jyeorb.
