Mariana Ostanik – Designer

I am an illustrator and designer focused on children's publishing, with a cute and magical approach.

Overview

Mariana is a talented children’s illustrator and graphic designer with a passion for cute and cozy things. Her love of art and imagination stems from her childhood, spent surrounded by art materials and creating characters for stories she had imagined.


With a degree in Graphic Design from the University of Estate of São Paulo and a Master’s in Science from the University of São Paulo, Mariana brings a wealth of knowledge and expertise to her work. After years of working as a graphic designer in Brazil, she and her husband moved to Portugal in 2018, where she made the decision to fully dedicate herself to her dream of becoming an illustrator and designer dedicated only to children’s books.


Mariana’s work is primarily digital using Adobe Photoshop, but she also has a keen interest in traditional media such as colored pencils, crayons, and gouache. She incorporates elements of these traditional techniques into

her illustrations to bring a unique perspective to her work.


Today, Mariana works with publishers and authors from around the world, bringing her unique style and passion to the world of children’s and early readers’ books. Whether it’s through her illustrations or her graphic design, Mariana’s work brings warmth and magic to the pages of the books she works on.

Mariana was great! Super upbeat and fun to collaborate with. She had many great suggestions but was always more than happy when I wanted to go in a different direction. She was very fast and in fact, was able to beat our deadline by a couple of weeks. I would definitely work with her again and if she wasn't available I would wait until she was! Her art was even better than I hoped it would be. ...
