BLADE RUNNER: Spinner marker sketches

A few weeks ago @georgehull.artstation.com released a video of himself sketching one of his iconic spinner designs for Blade Runner 2049.
This enthused me so much I got my own pens and markers out and did three spinners of my own in quick succession on A2 paper. It was really good to just draw on paper again, something I haven’t done in a long long time and should do more of.
I didn’t spend long on them, and could have done loads more iterations.
