For his lasting contribution as a children's illustrator, Torseter was a finalist in 2014 for the biennial, international Hans Christian Andersen Award, the highest recognition available to creators of children's books.
[1] Torseter has qualifications in illustration from Merkantilt Institutt in Oslo (1991–1992), Skolen for Grafisk Design in Oslo (1992–1994) and Kent Institute of Art and Design in Maidstone (1995–1998).
He has illustrated many picture books, including the prize-winning Klikk (2004), which he also wrote.
Torseter works with both traditional and digital picture techniques.
The pictures in his books can be illustrations to the text, but also play and experiment with free drawings which contain details and stories with opportunities for exploration.
