From before, due to comments and my own thoughts, it was clear the blue would probably find its way to being the main colour. However I was not sure if light blue/purple would work so I did a darker test as well Which I prefer. I also did a test just to see would it would look like both dark but reversed again. I like 1 but feel its to light for a villain, though I could be wrong so feed back is wasn't wanted. I still feel the darker one is better due to it being a little more villainy to me.
Added her sidekick here so you could get the colour contrast between the two so they can complement each other.
