I used a Platinum Preppy fountain pen for this. I like how it makes me kinda happy looking at it haha. I made this into digital form ( made it a little happier with more smiley faces) and put it on my Redbubble and TeePublic.
The third book in the "Little People, Big Dreams" series is about Frida Kahlo. I have to say, I had the most fun illustrating with this book cover. Beautiful color pop and written by the fabulous @mariaisabelsanchezvegara
