Wow!
This is a serious novel you have here. I felt a good level of connection and intrigue just by reading your description. "What would you see when you are dead", it reminds me of Wayne Dyer's question "How long are you going to be dead?"
I'm definitely a sucker for a memory blank beginning adventure (it never gets old for me). Definitely a good original source and adaptation. Illustrations, CGI's and photography, music, etc.; you guys really played with the medium here.
Good luck with this and every other project!
