Protoss DT Hero and Dark High Templar

Here's some Dark Templar concepts. As for the idea of the female Dark High Templar, I did it for fun, not sure how they would be significantly different from normal High Templar. I've never seen any female infantry for Protoss so I tried to figure out their anatomy, hopefully it looks obvious that she's female.

Someone over on SC's facebook (where this is also posted), said that High Templars are ones who embrace the Khala, while DT reject it. I admit I'm behind on my SC lore, but I like doing art that have twists on what's familiar. So I'd like to think DT figured out a way to harness similar High Templar powers through other means.
