A lot of the humor feels either cliché, strange, or overly sexual. Sorry, but I don't think that the Miley Cyrus thing is funny, and the entire second paragraph (in the introduction) is over the top to the point that it isn't funny. The second and third sections also suffer from this problem of being over the top sexual to the point of not being funny. There is some good stuff, but a lot needs to be re-thought.
Overall, the concept is very good. Having an article on Satan is to be expected on a site such as this, but there are some clichés, and a lot of the overly sexual stuff ruins it.
Prose and formatting:
Everything is very good grammar and prose-wise, but maybe it becomes less encyclopedic and more outright satiric at some points. This is a problem of voice and goes along with the humor comment. I think that having a very serious voice and saying something ridiculous is the best way to do it.
The first, second, and second-to-last images are very good, the Nixon one is a bit over the top (maybe that's also good?). Captions could MAYBE be used a little more effectively, especially in the banana bread image.
I just averaged your scores
Overall the concept is pretty good, and the images are good, but I think that the humor could be improved to be funnier. IT just requires some re-thinking and removal of clichés and over the top and not funny sexual stuff. I look forward to the updates!
