The challenge was to complete a tile starting with a blank canvas without any strings (i.e. pencil guidelines). The eyeball looking design wasn't intended, but that is part of the fun of Zentangle, you never know what you'll end up with!
Patterns used: Arc Flower, Copada, Floatfest, Dutch Hourglass, Msst, Diva Dance, and Fescu.
The ORIGINAL of this piece of art is available on my Etsy shop (while it lasts)!
