First Children's Book

It has been in the works for over a FULL YEAR now, but my children's book, about a little girl who spends the entire day in pajamas, is going to be published in Spring 2021. (For more information on this, email me or feel free to message me.) 
Below you will see the image we hope to use on the cover. This little girl, Sophie, has been forming & changing for a year. My biggest focus has been on how I could make Sophie seem like a self-confident little girl who decides to do something unique & not let how others react bother her. I think it teaches an important lesson in emotional health & well-being.
