Adult to child options
I actually used your custom coupon book as a gift for my niece, and it did well. But it would be GREAT if you actually had child to/from adult relative/ mentor options in your customization features (or even a child to child option). Such as a child body size option in the characters. And this could open up even more coupon event options too. Either way, I'm very happy with my coupon book and will likely use again for my niece.
