What sets it apart
In the art section, Drawing covers anything done by hand, Sketch covers loose pencil work, and Illustration covers finished coloured pictures. Line Art is narrower: an image built from outlines with little or no fill, usually one colour. That is why technical diagrams — molecule skeletons, GHS hazard symbols, bridge schematics — sit here next to animals and landscapes.
Checking the line
A good line drawing keeps an even stroke weight and closed shapes. Zoom in to full size: the line should be solid, not broken into dots by compression, and there should be no grey haze around it. If you plan to colour the picture in, closed outlines matter even more — a gap lets the fill leak out.
Size and use
Outlines scale up better than any other kind of raster image, which makes this category the best source for colouring pages, laser engraving templates and large wall prints. Thin hairline drawings, on the other hand, disappear when shrunk to an icon; for small sizes pick those with a bolder stroke.
