That is lovely (though I personally like the rightmost abstract blobby style from the first pic)
Hahahhaaaaa, I just noticed his fingers moving. That's magnificent!
Random suggestion for candy cane: make the whites whiter, the brights brighter ^_^, and maybe add a sorta thick black outline, and it will look like perfect cartoony foreground scenery.
That shading on the hat looks like something I would do, which means it can be a lot better and more realistic
(the shape of the shadow seems random, I mean).
No other crits save for animation, but you probably already know that it doesn't look extremely smooth or natural (look at real cloth billowing, the bottom of the coat should whip out after the rest of it, in a rippleish motion)
Fresh out of ideas for shading the hill =( I can see why you're stumped (I would keep to your simple shading style, tho)
