It's definitely great work, and yes I would buy something like this for the grandkids now. I could easily see this in a scholastic book fair.
One thing I would probably look at changing since it is meant for a younger reader, I would think about looking for a slightly less decorated font for the words.
Another thing I could see kids enjoying this as a short narrated cartoon as well. Doesn't really have to be super animated it could be just a page-turner on YouTube or something. Like an audiobook with pictures.
Thanks so much for the feedback.... I have really been looking at the font as well and am thinking about finding a bit simpler one.... and I think a motion comic would be so cool :)
I really like the motion comic, I have seen several of them done that way before. I did find this resource for a reference when you get ready...
