Animation's choppy and slow, and the looping and snow kinda just didn't do anything for me really. Though nice message of living off the land completely free and independent which is, or at least that's how I saw it and I could be wrong about it. And then there's the setting of the forest and mountain areas, diggable and distinguishable from the characters which is also nice, tho the man can sometimes blend in with the forest bits but not that big of a problem due to the saturation saving it.
The pacing is what really got me shooken up, maybe that could be fixed by either scrapping the spring bit in the beginning or showing a progression in time that would warrant the shift between green and snow. And in terms of animation fixing up the inbetweens for smoother rates would work. Other than that, rock on dude.
