Great Movie
One thing I don't understand is when people don't give credit to voice actors. Well in this case it's different. If it's in the best interest of the girl that her name not be given out, then I guess that's the right thing to do. Otherwise, a great performance deserves credit.
One of the best things about this movie was the style. The design of the girl was simple and cute. The facial expressions were faithful to the narration.
As for animation, one of the greatest things was the lip-sync. A lot of people don't understand how hard it is to match lip movement to sound. Then there's a difference between smiling talk and upset talk. Great job with both. There were only a few awkward tweens at the end. What you did was do a slow movement of both the head and the neck. It may have looked better if the head and neck were separated into two layers and the head was the only thing being tweened. Don't get me wrong. The animation was fantastic.
The music played very nicely during the actual cartoon. It was a nice choice for the situation and the character.
Writing wise, you had me. For the longest time I thought you animated actual audio of a girl reading a letter to her deceased father. Great job with the dialogue.
Don't listen to people who say this doesn't belong on Newgrounds. It's an amazing piece of animation and Newgrounds deserves this. Keep up the good work.
