I've been dealing with the fear that my comic is trash. I replay the whole story endlessly in my head day in and day out, improving scenes and adjusting dialogue to better fit my characters, but I still feel as though it's unoriginal. I mean, people that turn into wolves, how more cliche can one get?
I justify to myself that the story makes up for the overused trope, but in the end I can't always convince myself that's true.
When those negative thoughts get me down, I have to really work hard to remind myself that even if my comic's plot has been done a million times, I continue on because I love my characters.
