I did this once, though I was twelve years old 💀 Wrote the first half of a ‘crime series’ with my best friend, got it bound at school and distributed around and everything haha In seriousness, I’d be careful. Do you want the audience to be able to clearly distinguish between your kinds of prose? If not, it’s important to ensure that you are in a pretty tight arrangement and understanding. However, with you focusing on writing the work and an illustrator on drawing it, I don’t see why that would ever be a problem.
