Adilson Farias is a Brazillian children’s book illustrator based in Curitiba.
Farias works both in watercolor and digital media, using the characteristics of both to advantage. His work in watercolor often has a loose, informal charm in the application of color. In his digital pieces, he combines precision line work with a jaunty drawing stule and textural applications of color.
His website/blog is in Portuguese, but is easy enough to navigate. You may find it easier to get an overview of his work in his Behance portfolio.
