Hi Charlie. Were you going to send this out to publications or just going for feedback? And am I right in thinking that when your MC adopts these different personas something very bad happens? ( I'm only wondering that from the 'sinister smile', the 'smooth, cold metal inside', the wolf howling. They suggest violence is coming)
If so, I'd say trans psychopaths might not be so welcome in the current climate (read the backlash against JK Rowling's current thriller). Just my opinion and I'm not saying this subject shouldn't be explored necessarily, but rightly or wrongly, I'm guessing it would be a tough sell just now.
I also find the stereotyping of his female skins problematic too - from the mousy Julia with her glasses, the common Chenise and the red stiletto wearing Scarlet. I'm not saying these women don't exist, not saying a troubled individual wouldn't use them as personalities, just that they're stereotypes.
Forgive me if I have your intentions wrong.
Perhaps the others are right in that it needs some clarity and direction. Perhaps we should see your MC out of her dressing room and venturing into the world, interacting with her target, the gorgeous Julio?
There's books writing here and I'm really interested to see where you take this story next.
Good luck with it all
