I'm in awe.
When I finished watching this, I felt very very happy somehow.
This is a very simple, yet brilliant piece of art. It has a good moral, and the main character, Nim, is as cute as my puppy.
The graphics are jawdropping. You seem to have made everything in great detail. The snow was just amazing, and I couldn't believe my eyes when I saw the smoke coming out of the chimney.
The music couldn't fit better, and it's a good thing you let the dialogues in your main language, Swedish. It gives the movie a more unique feeling, although that's not necessairy at all.
I can't find any bad thing about Nim's Winter Tale. It's one of the best works I've ever saw here on Newgrounds. A job well done.
