Thank you for the feedback DuallyElemental. I understand it's a lot of work. The good things is, I do not have a strict deadline for completion of the project, so at least we can be flexible with that. I am looking to split up the work amongst multiple people so that at least no one person will have so much work, so hopefully that'll help.
There are songs but they are already done, there is some animation/visualization of the songs that will be necessary but no singing (thankfully for me) and no voice over work.
Thanks again for the feedback!
