I had thought about black marble as well, then decided to go for the star field. Maybe I'll post a second with the marble one and take a vote on which looks better.

Yeah I know what you mean about filling in the spaces, I just was having some trouble figuring out what to put there. Maybe some statues of various creatures etc.

I think I spent about 8-10 hours on this thing and most of it was looking for and modifying the artwork for the deity symbols. Boy that gets a bit tedious after awhile.
