Yay! I'm saving my pennies!
It's cheating to use any work that has previously appeared in a coloring book.
Even if that coloring book has been out of print for years.
It's also cheating to use work that was in Tell Me a Story
, even though that wasn't really intended to be colored.
A bonus piece no one has seen before would be awesome!
(But isn't necessary)
It should have a theme, not just be random work.
A chance to win some of the original art with it would make me more likely to buy a copy.
Your coloring books are too expensive.
