A lot of hard work
My two cents: You put thought into this project and came up with a decent story. I agree with most of the reviews on the point about a "cookie-cutter anime," but tried and true works. The art could use a little work (one person mentioned arms being too short), but that's why we practice. The voice work was superb, but people only notice the audio when something screws up.
As far as the critiques, I found that the animation started off kinda videogame-esque, like "Hero, here's your quests. Embark on your generic adventure!" There were times when the villain seemed unnecessarially evil, which works if he were prejudice or sadistic, but he seemed a military thpe, so it seemed a bit off. As for the heroes, they appeared to still be vying for each other's approval, which is fine for the trainees, but that one super strong vet seemed a bit hollow for a character.
I'd like to see how this will progress as a series! Keep up the good work. Animating is no small feat, nor is a project of this scale. Good job!
