This one is interesting. The art style is very simple at first glance, but it's also very consistent, which lends it more of a professional quality. The blockiness and the saturated colors give me a whole Cartoon Network kind of feel.
One problem I have with the art is the lack of variation and dimensionality to it. The 'camera' is almost always looking dead-on at the characters, never from below or above or any other angle. This can make scenes with just dialogue uninteresting to look at, since it's just back-and-forth panels that look very similar.
The story itself has a big dramatic hook- fate of the world and all- but I think it cuts to the chase a little too immediately. Characters are introduced all at once, in big groups, and then immediately they all go to one place, and more new characters, then another, and so on... It's hard to digest and the pacing feels off. Since there isn't much buildup to each event or introduction, sometimes they can even feel random.
Overall, it's a promising start, and I see how a story like this could have broad appeal. Keep at it, and good luck!
