Thursdays #bandofsketchers prompt was angled. I took a digital drawing of a profile and added detail the decided to add angled patches as if light was blocked out in a checkerboard pattern. It’s slightly abstract, I hope it works! It’s a digital drawing I drew on my tablet.
I think this counts as a visual illusion. I took a photo of a mince pie tin and moved it round in an app. When I looked at it, it looked like some of them looked like craters and some like they protrude. I think this is because the shading is throwing the light in opposite directions. The middle row is the most confusing.
