Glad you like her! She's probably my favorite so far. I like the airbrushed background and neon-looking whip. Even though this is supposed to be an updated design, the background gives it a great nostalgic 1980s vibe to me.
As of moments ago, I sent my Thea ideas off to a new artist. Here's her dA page if you want to take a peek at her art style:

The big change for Thea will be a move away from frilly and towards ancient Greek/Roman overtones. It's not like Laya's outfit, though.
I also found an artist to help with the male characters, and am about to send ideas off for a Kain redesign. His redesign is among the least drastic I have in mind. His red outfit will be a one-piece mechanic's coverall, he'll be holding his psygun from the text adventure, he'll have mechanic's gloves instead of those silver bracers, and his yellow boots won't be
quite so yellow. His hair will be about the same, since there's nothing really that dated about it. Of course he'll be smirking. I'm debating giving him welder's tinted glasses (not goggles!) to have on top of his head, but I'm not sure. Anime characters with goggles on their heads is becoming so cliché these days. Every series has a smartass guy with goggles now.
So be on the lookout for Thea and Kain!
