Here's were I've got to so far. . .

Just a few details to add, for my purpose.

This is rendered using the Ps Find Edges function.

Over the years, nay, decades that I have been using this program, I have discovered all kinds of ways to make the art look better after it's been scanned. Today, I realized there was something I could do with these pencils.

As I got deeper in the "project", my drawings got tighter and tighter -- getting better seated back in the ol' saddle. This meant the jungle backgrounds became better defined. Making some of the earlier pages look kinda sloppy, at least to my eyes. But this morning it occurred to me that, since I'd spent half an hour or so scanning all the pages at high res yesterday, I could "clone" parts of my foliage from one page to another. Sometimes even flipping the original.

Quite an improvement! And imagining these pages being inked, I doubt that anyone will even notice.

SCIENCE! Gotta love it!!
