I’m just going to recommend WITCH to all of you. It’s not at all megaten related but it was what got me started on drawing all those years ago because look at the art
Here’s a website where you can read it. Since they’ve stopped officially translating the comics into English, some very helpful fans have started translating them from European languages. If you are interested in a subversion on the magical girl genre, good female characters (and villains!) and POCs that aren’t horrible stereotypes or nameless side characters, definitely check WITCH out.
(not the animated version though, it really doesnt do the comic justice. Actually the second season is actually really good. Don’t bother with the first season.)
One of the creators’ tumblr is here. Barbara Canepa. The other creators are Alessandro Barbucci and Elisabetta Gnone. They also collabed on another comic called Skydoll that’s aimed for more adult audiences, the art is even more gorgeous in that one.
