Great
You artwork is beautiful, and this flash was very well made. I know you made a comment that you couldn't find a voice actor for the old man, but in some ways I think that worked nicely, although if you worked it from that angle, the main character would have to be silent as well.
I would suggest improving on the spelling and grammar in some of the subtitles, though, for example, 'you' instead of 'u', capitalising "I", etc. I feel it would just give it a tad more of a professional feel.
Other than that, it was very good, and I enjoyed it. Well done!
