How to make files of colored pencil art for large-scale production?

Hi, I'm a little illustrator with no experience in large-scale work. I typically use Photoshop and Procreate for my digital art. I'm concerned that my drawing style may be difficult to convert to .ai format (it’s a style like using colored pencils to draw and fill, not solid filling). However, I've seen the work of other artists with a similar style who have created large works.

What is the best way to ensure that my drawings can be produced as large works?
