Mandala
It's so much fun to draw a mandala! I know you're supposed to meditate on finished ones, but my meditative process occurs while drawing them. If you'll click on the image you can see the detail, which is the whole idea of the mandalas I draw -- lots of small detail. Sometimes they look like an ant farm on a busy day.
I discovered the artist Edward Burne-Jones on my first trip to the Getty a few years ago. Afterwards, at the Getty gift shop, I even bought the poster of his painting, "The Golden Stairs," showing eighteen golden-pearly-gowned ladies (angels?) descending a long staircase, each carrying a musical instrument. I think it's a sort of spiritual-religious painting, but without any icons to know for sure. This drawing shows two of the women who were near the top of the staircase, without their instruments, which I sketched with pastels.
