With the design changes, I'm liking the blue here. It gives that "good" warrior vibe or warrior of light vibe. The blue can also serve as an good story element. It can say some about the tech in her world. The orange is also nice because it has a realistic touch to it. I think because of her role, the blue might be the better choice. But looking at the latest illustration wip, the colors being orange work to help the scene color break up. Nice complimentary colors going on with the orange an blue. Hard call to be honest. Hope this kinda helps. the new design is still aesthetically pleasing. I like the face a lot.
Edit: I think the red/orange flame might contrast the best due to all the blue on her body. Just a thought.
ok enough rambling. This is looking good. Best of luck on choosing and keep up the good work.
