She has watery patterns and fish on Her skirt, both Her symbols; and the skirt is divided into seven sections, which is a number associated with Her. The fish design is after a carved door. The book I got talks a lot about how Yoruba art is 'segmented', meaning elements arranged in sections or stacked one upon the other; I've tried to get some of that sensibility in the design. The background is after adire textiles, on which designs are painted in cassava paste (I assume very sticky stuff) and then dipped in indigo, the paste forming a resist that the dye does not penetrate (much like the 'mud resist' of India) but can be washed off later. I tried to pick designs that looked either watery or like stars to evoke both the whirlpool that is Hers and the whirling cosmos.
I'll do this (as I said) in acrylic, then do the outlines digitally. I've decided also that the outlines for Her with be in black, those of the background a very deep indigo blue, and those on Her clothing a dark purple. Though honestly I'm half-tempted to do it in watercolor. The drawing just came out so nice.
It's pencil on white paper, incidentally; it just scanned in sort of sepia-toned when I adjusted the contrast, and I liked it so much I left it.
