Touching story
The story and concept was great and very touching. It's nice to finally find an animation these days with a good story to tell.
One gripe though is the voice acting. I can tell english is not your first language. The voices sounded forced and were kinda hard to understand at points. Really, you should've either looked for english voice actors for the roles or do it in your own language and add subtitles. I've seen several people make flashes by doing the latter and they come out pretty good (Eg. Nightwayfarer), so keep that in mind for next time. :)
