It's cute, and the house is quirkily shaped and the design is very nice. The colours are great too. One thing I was wondering about is the dark smoke, I'm not too sure if you were going for it but it makes santa's factory look like an oppressive North Pole conglomerate. Totally works if that's what you were going for but the cutesy houses up front contrast with it.
Great job though :)
It's like that on purpose. While the elves are living in a wonderland, the factory is the opposite.
