Just thought I would see what everyone thought. Maybe a little C&C.

Wow, nice! Looks real at first 
Curious, how did you do the bushels of hay?
The hay is basically a cube with a straw image UV’d to it. A little doubling and stacking, then added a hair particle for the straw sticking out.
This scene looks too flat and the sleigh looks too perfect for an old barn scene. Other than that, the modelling looks great.
Cheers!
