"Running 'round in Circles". Just the push I needed.
Black and brown Sakura Pigma microns on Strathmore toned gray sketch 400 series. Tangles are Rick's Paradox (in a spin!), Shattuck, Punzel/Rixty and Emingle (triangulated). I also used PolyChromos, Fabrico gray marker, Zenstone and Prismacolor white.
And a Zendala tile with a PeelD variation (tangle by Franciose Lip) and 'NZeppel.
