Motion Capture? I would have been of the impression that that is too costly and high level for any small group to do. Usually only movies and games (ie. Gollum in Lord of the Rings) employ such methods. So is this CG, then, or classical animation? I have never heard of such a thing being done by anything less than those with millions of dollars to spend.
By the way, how old is your group? I saw that the group that is making the other one, ie. the one to whom this thread belongs, is all under the age of 14. That lends me some serious doubts, as I know that my own level of artistic understanding, especially in so far as written dialogue and the like, was quite lacking at that age. My own little 11 year old sister, who is the best writer her age that I have ever seen, could not accomplish something such as a script even when will be 14, simply because she will lack the experience and understanding of words and forms. I, who am a decent writer in my own right now - or so I should like to think - would have grave difficulty in putting together a cohesive script of such a vast story, and not appear either childish/simplistic or overly formal (the latter of which would perhaps be most commonly attributed me.) And this is only so far as script writing is concerned, which is nearest my own understanding (as a would-be writer.)
we just started only about a month ago, and we're finishing up the script and will start animating soon
That particularly concerns me. I cannot see anything of such required length (what is the length?) being completed in less than a year. To actually write the script, I would think, would take months, and twice that for editing, and re-editing, until every sentence and line and part is absolutely perfect and as you wish it. A month is likely not even enough time to step away, leave it be, then come back with a cleared head and re-edit. That is my view of such things as someone with a few years writing experience (on the CT vein in fanfiction, and on other things.)
The rest of what goes into such a thing, such as technical expertise, artistic ability, acting ability, etc. I would have difficulty commenting on.
My apologies for my doubts, but I am not sure that anyone of such a young age have the experience to create something like this. I may be wrong, I speak only of what I know for myself.
