I believe many challenges happen at this time of the year, haha
Ink it media limited to trad and I'm not sure about Drawloween, but here is Artober if you're interested: http://kazenishi.tumblr.com/post/165621122920/
It kinda miss the point, imo :P
There are so many, including pokemon and other themes, that it sounds unfair to be part of inktober and draw digitally; let trad artist have their fun on the tag :D

Is Artober a different list then Inktober and Drawloween?
