Looks great but I have some holes to point out
Although the feel of this series is absolutely stellar I wonder how you would have a "scientist" 2000 years ago.Wouldn't they have been alchemists or at least wise men or something?Just a semantic but you should word it right I think.
Next, how would the guy who finds the book know to read what would surely be ancient aramaic or some other archaic and forgotten language.I would of course accept that he's a reincarnation of the "scientist" in question but make sure and cover that base.
And now my final grievance...The syringe in the end of the trailer.Looks suspiciously like the stuff in "Reanimator" that was used to render the dearly departed ambulatory again.Would a body snatcher of 2000 years ago have had a syringe even remotely similar to the one shown?I'm no archeologist but I tend to think he wouldn't.
Besides the, the narrators voice is cool and fits well.Your style of drawing where everything seems rusty and worn is great.I can't wait to see this series start in earnest.
