I am just getting into Affinity Designer with the hopes of using it for character illustration for a book. I am trying to find ways to shortcut my work. I want to create a library of common body parts for the characters that I can use across all characters. I want to create all of the body parts once and swap out hands, eyes, and mouths for each character as needed. Is Affinity Designer a good tool to do this in? Are there any tutorials that show how organize and swap body parts to a character?
