Coloring Book Project... Feedback please

I’ve produced a coloring book and they arrive this weekend… woohoo. Each page (45 images) has a zapcode that currently triggers an image of the painting to come up as an aid if the viewer wishes to use it that way, or just to look at it… I’m thinking about adding other things to this, as it seems too simple. Adding the title seems like a no brainer. Do I add a link to the time-lapse video of me painting that image? Do I add a link to the page on my website where I have that painting? Or the products that use that painting? So many options… thoughts please…
