Edgar Allen Poe's influence shows primarily in the dark nature of Burton's work. His influence also shows in more subtle ways, such as the untraditional and quirky characters that are usually the protagonists. Also, both of them use protagonists in their stories that clearly have good and bad within them, rather than just good (as is typical). Mostly, Poe's dark fantasy influenced Burton to follow the same genre.
I believe the colons should be placed as follows:
1. One thought kept crossing Jen's mind as Friday approached:
2. included the following: life, liberty, and the pursuit of happiness
3. cultures:
on the first sentence you are separating her thought from the statement
on the second, you are separating a list from the statement
on the third, you are separating the two different types of cultures from the statement.
I really hope these are correct for you :) good luck!
