Two "Golden Stairs" ladies

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.
