Looking To The Side
Anime art is specific and mysterious with the "looking to the side" tag. Characters often look left or right, with their heads facing forward or slightly turned. Artists can convey a character's emotions without speaking. When a tsundere character hides their care or is deep in thought and does not want to talk, this happens often.
Drawing a character looking sideways changes the face artistically. Making the iris and eyelid curve look natural takes skill. Artists use this look to draw attention to a pretty background detail or an out-of-frame character. Many sad or moody works use it, such as when a character looks out a rainy window or over their shoulder in a dramatic profile shot.
Sidewallpaper calms and unclutters your desktop. The character's non-screen-facing pose makes the art more natural and atmospheric. It is perfect for backgrounds with cool character designs without having to look at someone. It lets the piece's mood and lighting shine through.
