Spanish illustrator Rafa Alvarez has an impressive selection of works on his website. I like the way he sometimes uses coloured ink lines, almost like those in many animated films. There are nice strokes in his lines too. He has a good knack for well thought out editorial illustrations as well as advertising posters and comic strips.
Rafa’s clients include Playboy Magazine, Etihad Airways and American Express. He has published graphic novels and children’s books and is currently working on interactive ebooks for the iPad.
