Book illustrations for 2 pages/diagrams.

I'm writing a long book, but I really need someone to illustrate 2 locations in the book. I have some rough horrible drawings but it would go a long way to make these come to life.

First is a basically a fancy diagram of how planets are lines up in a universe.. My version of Heavens.

Then a domed area call sanctuary with cut out of the front, side and top.
