Welcome to Artist Forum, m3shin!
Doodling is a valid, full-fledged artform and arguably, one of the earliest ones. If a doodle completely lacks any repetition, we can consider it an abstract; with repetition or some kind of sequential structure, it can be classified as a pattern, most popular in graphic design, especially the textile industry.
Without the rigidity of a definitive, representational form, doodles can often express something intangible, primal and universally unique to each viewer that other artforms may fall short in.
