Very well done.
You deserve a long review.
The first thing I would like to say, I hope this gets to the top. The animation in this must have taken you a very, very long time. The sounds are all very good aswell, the voice acting VERY nice.
Let's start with this.
Graphics - You kept the way you drew everything the same the whole way through, consistant, highly detailed. Although at one point in the movie, he is missing his (from his view) right bicep, but I ignored that.
Style - I love your animating style, your story, and everything about this animation. I don't see anywhere you can improve here.
Sound - The sounds and music all fit the scenario very well, but when the rock was being slid to the side, I heard annoying crackling. That's why this didn't get a 10. Very well done.
Violence - The action was just what it needed to be. Not too action centered, just the way I like it. And, the action scenes were drawn just as well as every other part. Definatly full marks here.
Interactivity - This is the one place I could see improvement. I would like to see an option, at the beggening of the movie, to have it automatically change quality, in the player, at times where it was going to be very graphically intensive. I found that changing the quality constantly was getting a bit annoying, regardless, you still got my 5.
Humor - When that crow said "Oh crap" I laughed. I wasn't even expecting any humor from a video of this type. So, it was unexpected, and very funny.
Overall - Well, you fucking rock. This movie was very, very well done, and I see it having a place in the top 50 of all time.
Goodjob, and I hope to see more.
