It's been said, but...
This is really great! The sheer length of it is impressive. The art style wasn't really anything super new, but it certainly did the job. The story is fantastic, and the fact that they flow was a little akward did little to detract from it. Major flaw? SOUND. This is the MTV period - everyone has ADD now. If the viewer doesn't have every possible sense satisfied, they're going to go look at something else. This movie would have been AMAZING with the right background music, and maybe a little speech, just a word or two here and there. The animation was a little... underdeveloped at times, but it's evident that it is the product of practice, and will only get better.
Overall, great. Keep it up, I look forward to seeing more from you.
