Since I was disappointed by how It: Chapter 2 portrayed the Spider from the book (I mean, the spider-clown taur is cool but I really would have preferred it if IT continued changing until it was a full blown monster spider by the end with no clown features), I decided to draw how I invisioned the Spider, both when I read the book, and how I think the movie version should have been, at least a little. I should have added more monstrous features, maybe some tentacles or more spikes to give it a Lovecraftian feel, but oh well.
The Spider up top is female and pregnant, like she was in the book, but it's kind of hard to tell because that tongue is in the way (the said tongue that was used for the Ritual of Chüd)
The Spider on the bottom is basically the same take, except it’s not female or fertile, and it has all of the Pennywise markings, colors and whatnot.
