What are everyone’s thoughts on putting an author bio or illustrator bio at the end of the book. Do people do that for Children’s Picture Books or is that not necessary?

This is the latest illustration from my illustrator. My book is about a farm dog (Daisy) who has gone missing. While walking the farm and feeding all the animals, the farmers asks if anyone has seen Daisy. What are your thoughts on the illustration? Also, I am not sure I’m sold on the title. I’m struggling with this one. Thoughts?

I feel like a little kid showing off, but I couldn't sleep last night. After several hours of tossing and turning, I decided to get on the computer for awhile. I decided to get on Canva. Big mistake! I ran into something called Magic Media on there. Magic Media is still in beta mode, but it will make videos for you. You just type in exactly what you want and what style you want, and it does it. This is free as far as I know. Will this be good for making book trailers, reels, and other kinds of writerly things? Anyway, here's what I did. It's a video and I hope it works.

I just found out very recently that it got approved and published on Amazon! Thank you very much Harleigh for fixing the error and re-uploading the file, and everyone's advice on here was also really helpful! I was getting a notification about an error with my activity book on KDP for a while, and I was stuck when it came to publishing it. I'm really glad and happy that my activity book is published now! 🙌

Is it better to have illustration files saved in png, jpeg or something else? This is the y first book and my illustrator’s first book and she asked me how I want my files. Thank you
