The Amazing Comic World Builder for Procreate

Pretty good.

The pack contains a bunch of templates useful for comic book artist who want a quick reference or stock item for their work. this includes explosions, buildings, space stuff and the one I really found useful, a thumbnail template for storyboarding pages and laying out a comic. It also includes a bunch of brushes, all great, as every RSCO brush is, and a font called 'Pullbox' which is really quite nice. Oh, and the word bubble templates are also really great for place holding. This is a great pack but im not sure how much it supports already seasoned comic book artist or hobbyists. If comic books are new to you, I promise you will love this pack.

A whole universe in one pack

This is basically a cheat code for making comics. It literally has everything you need to get started and keep going. Fonts, templates, textures, brushes, character sheets. It’s got it all.
