Made with Chibi Paint, Linux MyPaint, and GIMP.
A redo of one of my Computers Club Drawing Society drawings, with fake drips and textured background added.
When I worked in acrylic I also used to add fake drips after a drawing was finished, to give the impression of painterly gusto.
I would put down a spot of color, load the brush with water, push down, and let gravity do the rest.
