So much, done with so little.
not a (visual) artist, does this style have a name?
getting imperfect scribbles to look that good takes skill, no need to be that modest
Is this done without raising the pen? It’s an interesting and cool piece of art.
No I raised my pen a few times. I was trying to force myself to draw as quickly as possible, so not lifting my pen trying to put down as much as possible with one line. I was also laying the weight of my hand heavily on the pen so it left thick shaky line and I was enjoying the aesthetic it produced, it also helped me care less about the lines being perfect and letting go.
