What do you think of this (part of chapter 1)?

to indicate its the 1800s you could change their language and if it's in London then i think you should give them an accent or something, unless their like foreigners or tourists. i thought the beginning descriptions were well wrote and it painted me a picture of the eerie night sky on that night in London. It would be interesting to see the gypsy be anna or make an evil dark magic kidnap Anna and Levi would have to save the world from destruction and save Anna. You could also describe London in the 1800s by looking up pictures and trying to describe that. Try to explain that everything looks ancient-like and sort of old fashioned. So people back then would probably wear suits and dresses in that age. Good luck with your story!!
