I love Knot Work art whether it's Celtic, Norse or some other form, I love knot work designs.
I take the classics and put my own spin to them in style and form, but the general technique of knot work remains the same.
My series, I would like to suggest, will be primarily in black and white. The idea is to eventually make them into coloring book pages (or sell then as such through Neonmob). The rares, variants, and such will be combinations of full colored art, sketches (WIPS), and alt colored variations.
The theme of the story behind it is more educational / informational. Many of the animals and beasts will be based on either real animals, or mythological creatures. The card descriptions will offer a snippet of such creatures information.
