Hm.
Well, the narration and voice acting in my opinion is very well pulled off, especially compared to others that I have seen. The story, coupled with the beautiful music, was enough to send shivers down my spine when I watched this.
Now, on to things you could improve.
The animation seemed very choppy at times, and the art work was, and don't take this the wrong way, not the best. The story in parts was also very choppy and not very well illustrated. However, the story, thus far that I can see, is very touching, and the voice acting really makes this good, even if you're not exactly a professional artist. Please continue on with this series, because I love it very much! Try not to listen to the people too intent on flaming you for your flaws, rather than praising you for your advantages.
