For the person asking about starting a comic: ALWAYS script first. I’ve noticed that artists who decide to wing a comic with no scriptwriting beforehand almost always fizzle out. And you don’t need a super-detailed panel-by-panel script - I use the “Marvel method” where I write important dialogue and what I want to happen on each page. You can either script out the entire storyline or do it chapter by chapter (script a chapter, draw a chapter, script a chapter, draw a chapter, etc.).
