Hello there! On W*ttp*d, where my book is also found, I'm able to put photos within each chapter of a book.
Here it's a little different, so to read character bios and a mini cartoon I drew for each chapter of the book, click the link to the google doc below!

ps: I'm not the best artist, it's just really fun for me and maybe easier to visualize certain scenes and connect with characters more. So if you wanna learn more about the characters and/or look at my mediocre art skills for a non-artist, click the link!
