Needed a break from Inktober, and wanted to do something with symmetry, not unlike a Rorschach inkblot test. 

The first was done on the iPad Pro in Sketchbook Pro, which I felt I'd been neglecting for some time. 

The second followed that same day, only using an iPhone 7. I normally don't care for the more gimmicky brushes like the ones with glow effects, but this one works.
