Based in Darwen, UK, illustrator and designer Chris Thornley, also often referred to as Raid71, has drawn these beautiful and minimal illustrations as an exercise of warming up before a day of drawing.

The collection, titled Minimal is Good, is based on two basic rules:

1. One line (occasionally there are two or three).
2. One minute to draw.

Thornley explains:

After a few days I started to focus more and more on simplicity/minimalism; What was the least I could draw and still convey a person/emotion?

Often depicting a female form, Thornley's illustrations, which could also be defined as line art, are simple and brilliant. Lovely work.
