interesting
Visually, you have a much more original style than i expected. I actually really liked the ink sketch look, and you used it rather well. It was simple enough to not get cluttered, but detailed enough to give your work some depth. However, you do need work on it. I found some portions of it too dense, such as the rooftop (especially the wall) and the pictures at the end. There was just a little too much ink, and the image became grainy and busy rather than detailed or expressive.
The animating was indeed a little jagged, but it was mostly the small movements the characters made, again, most notably on the roof (the character in white especially). Walking, though, was good and smooth for the most part.
The music was simply and a little repetitive, but it faded nicely into the background and didn't really come up much. I'd say it worked fairly well all together.
I do very much like the message, too. It's a little frightening to think how the simple push of a button can change someone's world so completely.
All in all, you have a solid animation. A little rough along the edges, but it's your second work, and quite frankly, i'm impressed with it. The fluidity and "touch", i suppose you could call it, will just come with practice and experience, which i'm sure you'll rack up plenty of as you (i hope) continue to experiment and produce. Whatever your score here, A+ for the effort, sir. Keep it up.
