Google neurographic art. It's interesting reading and very calming to do the lines. Tell your grand-cat that yes, I do take commissions.Not even sure what you mean by neurographic, but I love this cat, and my son's cat wants to know if you take commission work....Google
Quite vibrant. I love watercolorView attachment 48920
9x7 watercolor and ink using Micron 01 pen and STA Lictin brush pen in sketchbook done last week. I started a neurographic piece with the wavy ink lines then decided to incorporate an animal such as this black cat. A fun exercise.
