He grew up watching cartoons, playing football, and drawing a lot. These days, he doesn’t watch as much TV and only plays football once a week, but still has the joy of painting every day because for the last ten years, he’s been working as a professional illustrator for different print media. What he enjoys the most is illustrating books for children and teenagers. In addition to illustrating almost fifty books, Pablo also does character designs and board games and collaborates on designs for schoolbooks and magazines with various worldwide publishing companies. He is self-taught and his illustrations are mostly computer drawn, but he always adds textures that he makes with pencils, crayons, acrylics, and pretty much any material that lets him gets messy like when he was child.
