I wouldn't call it seasons, because I'm not making television. But I am mentally workshopping an idea for a sequel to Trespasser and a prequel, starring Cathrine my current protagonist's mother in her youth.
I've also divided the main story into 5 different books, which I've decided to label as 'chapters', because they are all portions of a single larger narrative. But I do tackle each book as their own little entity, with all new designs and its own isolated mini-arc.
Book 3 is most notable so far, as I'm overhoaling the entire artstyle of my comic by using a different rendering technique as well as drawing on a larger canvas.
