EDIT: From Nintobervilltch 2008, the progenitor for my annual Nintober project. Back then I only sketched 11 Nintendo villains rather than 31 monsters. It's 2012 and I'm redoing the old artwork and dragging them into the new template to make it one continuous project, if you like!

I must say updating the old artwork but keeping the same pose is pleasing. I couldn't do it with everyone, but it's quite cool when it works.
