Trying to narrow down my concepts. I've come up with what I feel is three solid choices. I'll field opinions on what direction I should go.

Here are the sketches/silhouettes. I've broken it down into these three concepts.

Shock Angel
Most of our imagery of the winged human comes from Babylonian myth. I decided to delve that history a bit to showcase a costume that was less predictable fantasy wise. I think giving her these wild electrical spreading wings would create a very impactful image.
Warrior Marionette
My grandmother watches a lot of Chinese Opera. I had an idea of a puppet with one of those highly detailed opera masks. I think that would be quite menacing having floating body parts coming at you with threads of electricity binding them together. The master would ride on a floating cloud above it and manipulate it with her "strings."
Tesla Mecha
I love steampunk, and this is more than likely tried before, but I thought it would be fun to play on a 1800's mad scientist mecha wielding tesla coils. They look cool as hell, and I think I could really make this sing. This would probably come out fairly pinup-y. Been awhile since I've leaned into that! Might be time to flex that way again.
What stands out to you? Anything you'd like to see fleshed out?
