A character I have been rather loving the design of lately from the Multiversity Thunderworld, she only really appears twice in all of Shazam history that I know of but I love the outfit and design.
This was more or a test for me than a casual drawing.
I did what I could to get the body positioning right, I tried to get all the proportions correct and although its not 100% it is pretty close.

I need to work on my knees, my hands and my torso, also i think the boots are a little thick.
Anyway here is Miss Sivana. go read Thunderworld -its fun silver aga-esk goodness.
