Well, I'm afraid I'm going to have to agree with everything Psyches said, and more:
For a long time there was a parallel dimension with humans and instead of animals there was anifals. Anifals are magical creatures with special powers; some can even activate natural disasters. Every time a human is born in the parallel dimension (earth is called seola) an anifal comes and when the human is born their anifal appears to them to keep not feeling lonely and to talk to. So this is about a group of chosen kids who have to save seola and the anifals by fighting with the most deadly creatures ever!
I would bet any amount of money that you have recently watched the Golden Compass (or Northern Lights as it should have been named.) The whole prologue thing is rather like the voice that speaks at the beginning, and the whole concept is identical (having animals as partners that are part of their soul, and in a different dimension, and how they're their partners when they are born, etc.)
As for the whole symbol thing, while intriguing, you list it all so that no body really cares. What you need to do (and I've learnt this from Crimson) is show us, rather than tell us.
I mean, rather than saying 'Ruzo wears this, has this on his clothes, and has x anifal,' you could have used the first chapter to talk of an incident where they were doing something. I mean, I don't have a clue what sort of power Pegasus has, but you could have had it so that Ruzo was playing in the park or something (Which would allow you to explore his character a bit more) and then there could be some event whereby Ruzo discovers that his sun-symbol has some mystical power. I don't know, he could be kidnapped or something, and the sun symbol could have saved him. And with the amount of characters you have, you could have wrtitten a massive old chunk on just introducing the characters alone.
Also, none of the characters or anifals have a personality. It's all very well and good saying 'I was going to do that later on,' but you need to have something right now
in order to catch the readers attention, and personality-less charries do not attract readers.
I mean, you have a great idea with the symbols and all, but your writing style and concept is just a bit lacking. Why don't you just drop the whole 'anifals born with them at birth' thing, and make these kids special. So, everyone on this Seola planet doesn't have an anifal, but these symbols mean that these eight kids do. Get my drift?
Anyway, keep it up, I want to see your writing skill blossom, because I know that you have the potential within you to do well. Listen to our criticism, but don't beat yourself up over it; without criticism, we can never develop. If that's not already a famous saying, I'll patent it so that I can be famous.
