Guess I found out where my inspiration went: into this picture. I spent close to two hours on drawing it. Too bad the color didn't go as I planned (a bit of smudge on the black, like always).
Still, I think this really worked out well. Now, I only have a problem... what'll her Ba (Spirit monster) be like?
I remembered that Lapis Lazuli was one of the most used gemstones in Egypt, so I placed them on her choker and her robe's rim, and I made the small tiara brooch from it.
