Picture Book Idea

Sorry this is so late. I was creating a little art piece to honor a young lady I know who just found out she has cancer. She's strong and has a lot of support.

A while back, I was doodling and came up with a cute picture of a girl. I called her Amelia and decided she was about five years old. Since then, I considered using her in a series of children's picture books. Now, I have only a vague idea about how to make a children's picture book, especially if I self-publish it. I'm sure figuring it out won't be that hard.  And I won't start on it right away. I have too many other things that need to be finished first, but it is something I want to do. Here is the little star herself:

Isn't she cute? :)
