Unlike oblique angles, which show the participants from the sidelines and create a sense of detachment (Kress and van Leeuwen 2006: 134), frontal angles generate involvement with the child-reader, as in them the viewer stands facing the Represented Participants so that their facial expressions, or at least their eyes, are gazing at him.
