While I absolutely agree that art is subjective, I see nothing in this that can entice a dialogue about the piece meaning or the emotion it radiate. I saw paint splashes on a wall that were more interesting because of strong pareidolia effect they give off. Talking about pareidolia, I have yet to see an artist use this strong feeling in their art. Draw random lines until you see something in them.
I actually do it ( not an artist ) as a form of relaxation and de-stressing. Leaving my brain inner mechanism do the work for me. I highly suggest doing it when feeling stressed. You’ll likely see a pattern in the drawings and it’s gonna tell you something about yourself. Mine is that the right hand is a stump as if amputated and it’s something i do really struggle with since birth due to a handicap.
