Overall, I like the concept of smilers put forth here. There are some details you'd expect from a powerful organization that must deal with smilers' presence, but I think they're balanced with the mystery that keeps them scary.
So, while I find the content quite good, I think this article could use a rewrite for style. As is, I think the writing doesn't fit the current Backrooms well. As the new Level 1 shows, wordiness isn't necessarily a problem. Nevertheless, I'm particularly bothered by the Basset-Frasier Intelligence rating description. Although the grandiose diction might initially look comparable with that of newer high-profile Knaff rewrites (like The Halls,) the fact that such lavish language is applied to what should be a relatively scientific description seems wrong.
I really enjoy this article, so please let me know if you'd like a crit on a draft or any other input. Thanks!
