Coloured round things

One day I had an idea. Coincidentally, that day I also had a lot of time. So I implemented that idea and made this.

It looks pretty simple, I guess, but it was very time-consuming.
I painted pieces of paper in different hues from yellow to dark blue. I used pearl metallic acrylic paint to give the shimmering effect. Then I punched out tiny circles from the pieces of paper.

After that began the tedious task of arranging the tiny circles into concentric rings.
8 hours (and a nap) later, I was done. I painted the background black and did a bit of doodling with a gold pen.

Same piece, different angle.

Ta-da!
