I got that.
Everything is handdrawn and inked first, then scanned. Sometimes, I decide to switch to vectors for some areas, but I don't work in Illustrator, I work directly on PS for everything (the old PS7 no less). It limits my options (like lines), but I prefer not to switch programs during a project, particularly when done in one go.
But the other project, if you want to get anal about it, has something like half the outlines not visible since everything is so dark. If we're talking about doing things differently, all the lines could have ditched. I think the coloring on the character would have had to be changed a bit, but yeah, it would have worked.
