"A letter to Hay Din" is a story about Mala and Hay Din, two dearest friends who met under tragic circumstances but eventually became best friends despite their differences in culture, race, and even language. When the time comes for them to say their goodbyes, Mala decides to write a letter to express her feelings. It's my first time drawing pictures for a children's book, and I'm got to learn things about the guidelines I should follow when creating one.
