I just want to point out that these images are for promotional purposes. Many of the effects used in these pictures won't actually be in use when the coaster opens to the public.
As the park is only open during the day, bar a few weeks at the end of October, the lighting and fog effects wouldn't nearly be as effective as they are in the pictures released today.
Having said that, the coasters theming sure does look absolutely fantastic, even without the extra lighting and smoke effects!
