hey there, stranger!
I finally got around to watching this!
I have to say, the visuals were much better than I anticipated from that banner in the audition thread. Even if the art looks a bit unpracticed (and I'm willing to give the benefit of the doubt, since you said there was computer tracing going on) I still like the over all style of it.
But, the one thing that really bothered me (so much so that it's almost the full reason for taking off 3 stars) was the lack of voicing in some places. As a voice actress and a producer, I can speak very strongly from all angles.
If you have a deadline for the completed work to be done, then you need to set a deadline for the VAs. The deadline should be a few weeks ahead of the completion date, plus and extra week or 2 for padding. Those padding weeks are in case the VAs need to reschedual. They should let you know if there's a conflict at least 1 week (if not more) before the VA deadline (that's just out of respect and proper VA manners). If that's the case, try to arrange something.
Of course, if the VA can't get things done on time (especially if you've given extensions) then you need to sack them and go to the understudy; your work shouldn't have to suffer because VAs are being difficult.
You should never post something in this condition, because it will look half-assed; even when other aspects show a lot of time and energy.
In short, it was a good effort on your part, but you need to control your VAs; it's your project, not theirs, and shouldn't have to suffer because of them.
