Comic idea and sketch

I had an idea for a story the other day: A typical story of barbarians and wizards, full of topics and cliches, but the hypertrophied protagonist decides to quit and so everyone with a classic role gets bent as the story can not progress as expected.

I already started a 3 page intro (and I have a lack of “backgrounds” technique… should research).

By the way, Happy Christmas/Festivity!
