A little rough around the edges, but pretty good!
Here's what I liked about your movie: definitly the storyline- original, powerful, and creative- has a nice openning and it captured my interest. The characters' movements were realistic(for the most part...). The graphics were. . .not bad!(shows progress). You also had a great selection of music.
Here's what you need to work on: voice acting(sounded like some person reading the script). Sometimes the characters seemed a little lifeless or robotic(the giant, for example, was perfectly still and had almost no emotion). In some parts the characters looked a little distorted.
Ultimately, I think you have great potential. This movie was pretty good and I'm really looking forward to seeing the next one.
