Damned good, I must say.
It's very clear that you put a lot of work into this, and for that alone it deserves its place here on newgrounds. I couldn't tell you whether or not the story was very well told, because the story itself seemed rather random and... I don't know. Plenty happened, but the whole thing seemed rather uneventful.
Some sounds other than the music and the one line would have been nice.
It was good animation. You have that aspect of the piece very solid. However, there is still room for improvement, and I hope that you will make the effort to become more well-rounded, so that you can create things that aren't JUST "good". You've got loads of potential.
All in all, it's a good piece of work, and I look forward to seeing more from you in the future.
