Have you considered adding some kind of depth support that would allow you to make "3D" images by moving not only left and right, but also back and forth?
My first thought was that with something like this (https://www.stavros.io/posts/behold-ledonardo/wings-small.jp...), it would be cool to walk around the subject and have the "wings" actually furl AROUND them rather than simply in front of them, though that might take some choreography to make sure that your own shadow doesn't affect the image too much.
Another thing that I thought was that if you can also selectively turn on only portions of the bar, you could effectively create "windows" in the portrait as you did with the other set of wings (https://www.stavros.io/posts/behold-ledonardo/alexandra-smal...), which could work really well with something 3D-ish, where you can see through one part of the lights to a different background also generated by the lights.
I'll play a bit with the window idea, feel free to follow me on Instagram at https://www.instagram.com/stavroskorok/ if you want to see the progress (I post all photography-related doings there).
