Today's #SciArtSeptember prompt is "Microscopic", which doesn't really give me any ideas because it's too big of a subject and I'm usually drawing microscopic structures and patterns. So I decided to play with microscopic Radiolaria in today's drawing.
I tried using circle templates, to help with getting the circles more perfect. Hmmm...I think I like free-hand circles better. But it was good to try it.
