Catarina O. – Designer

I'm a specialized children's book illustrator and cover designer with an eye for detail, creating unique images that bring stories to life.


SCHEDULE UPDATE: I'm currently available for book cover projects only. And in May, I will start scheduling Picture Books from June 2024 onwards. Thank you!


My name is Catarina. I'm a graphic designer turned into an illustrator passionate about illustrating stories that capture kids' imagination. And I've been a freelancer since 2015!

My illustration style ranges from detailed and realistic to fun and bold characters. I've illustrated Picture Books for traditional publishing houses like Ulysses Press and Owlkids in the US and Canada, including a non-fiction title.


If you need a cover for your book, I'd be happy to help. I can create custom cover art and designs for genres like fantasy for Middle-grade and romance for Young Adult and adult audiences.

I love adding customized lettering and other details to the jacket, making the reader wonder about the story behind the title.


My favourite topics include animals, nature and character-driven storytelling.

I divide the project into manageable sections, like thumbnail sketching, line drawing, and colour finals, with room for your feedback and direction. The thumbnail sketching stage (storyboard) is crucial for establishing page turns, compositions, and character design, all of which will complement the text and help the message get across to the reader.

Besides Picture Books, I'm also available to create grayscale illustrations for chapter books or Middle-grade and respective eye-catching covers.

I don't ever use any generative AI apps or programs in my work.

When working with me, clients can expect friendly and professional service.

Middle Grade New Adult Picture Books
