Not discouraging a bit.
Wacom, if you buy direct from them, has a 30 day - no questions asked return policy. If I decide it is too hard to figure out I can return it for $10 and get the full price I paid back.
Granted, I may be a bit naive about just being able to trace my design and that's that. But, if I at least I'd have a template to go over with colored pens and/or paint (which I have) I could make a passable copy of the fabric - on paper.
To my eye, the proportions of the designs and blank spaces on the pickguard are durned near perfect, and that's what I'm trying to reproduce. So far I've not been able to do that by hand.
Here's another scan of the guitar...
