It's just so heartwarming...
You can't help but smile as you watch nim do what he does. This animation is a mild and comfortable cup of tea next to a warm hearth. Instead of the usual mindless destruction and violence that stinks faintly of the 1337 morons, we get this reassuring and beautiful piece of... art, to say the least. I especially liked the theme of a character from traditional folklore; from the Northeastern parts of Europe, like Norway or Sweden, from what I've read. It's obvious you're a professional, and it's nice that you've used that skill to make such a cute fairy tale instead of another mock-snuff movie.
